I'm having the same issue, under Debian Stretch. I tried it with Python and Python 3, also using virtualenv. This is my debug output:

(my-coursera)

It worked some months ago. I had the version 0.9.0, so I checked if it works by upgrading to the new version 0.11.4.

[aakuptsov]

Yep, tried virtualenv with Python 3 - doesn't work either.

[aakuptsov]

Something tells me that Coursera has terminated the access to its resources via the API.

[gerardbm]

Now it's working! I'm using the same command I used last days:

coursera-dl -u xxx@xxx -p xxx unix

I also had problems trying to loggin in the website, using the new formulary, from several browsers, several OS... Even I reset my password several times, until I could join using the loggin button from this URL (https://learner.coursera.help/hc/en-us), being that enough to start the session for the whole site.

@aakuptsov, try now if it works for you, as well.

[Isaac-the-Man]

I encounter the same problem too, on Window10 using python 3.6. I checked everything in the requirements.txt
I did the exact same the document says:
coursera-dl -u myName@gmail.com -p XXXX MyClassName
I also tried to wrap my username and password in double quotes, but that doesn't work for me too.

[aakuptsov]

@gerardbm
It worked!!! You're amazing! Thank you for your advice!

[aakuptsov]

@Isaac-the-Man

@gerardbm 's advice helped me: log in at https://learner.coursera.help/hc/en-us, wait for a minute (that was my case, at least) and after that try to run coursera-dl. I'm writing that comment now while one of the courses I need is downloading.

[pavelpy]

@aakuptsov
This method is currently not working.

[avidLearnerInProgress]

This method isn't working. Kindly suggest new one.
I am facing the following error:

$ coursera-dl -u XXX -p XXX cloud-computing
coursera_dl version 0.11.4
... logs ...
coursera.cookies.AuthenticationFailed: Cannot login on coursera.org: 400 Client Error: Bad Request for url: https://api.coursera.org/api/login/v3

Tried changing the password; yet its failing

[gerardbm]

Well, to be honest it was not a method to fix it. It only was a description of a Coursera behaviour related with this. I explained that to suggest that the problem is not about coursera-dl, but coursera.org.

It worked yesterday because 'correlation does not imply causation'. It was only a coincidence...

At this moment, downloads are not working, again. Coursera-dl has not changed, and I'm using the same installation, so clearly the problem comes from coursera.org.

There's no solutions for that. Just wait and keep trying until it works.

[Isaac-the-Man]

@aakuptsov thanks for helping
However I am still facing this issue. I tried logging in and I waited a few minutes, but still nothing really changed. I guess it is has something to do with the coursera api.

[Isaac-the-Man]

@aakuptsov, @gerardbm thanks for helping it worked! Just have to log in with the link you provided. However, for me it takes about 10 minutes for it to work. Thanks anyway.

[Isaac-the-Man]

For anyone looking for help I want to point out that after logging in with (https://learner.coursera.help/hc/en-us), you must wait for a few minute than just keep trying. By keep trying I mean spamming your command over and over again and it will somehow work (at least it works for me, I need to retry the command about 10 times before it will work).

[Isaac-the-Man]

One more important thing I notice - you cannot open your browser to coursera while downloading. I closed all my coursera tabs and run the script then it works.

[aakuptsov]

I had this page https://learner.coursera.help/hc/en-us) open, I guess. Not sure about other Coursera pages.

[gerardbm]

That's what I did now and it worked after 8 attempts. It looks like the problem is on the server.

[aakuptsov]

At the end of the day I managed to download 2 courses that I needed. I'm gonna check later on if others that I might need can be downloaded through coursera-dl. But since yes, we all managed to download something, the problem is on the server. I wonder what that is and why the Coursera team either not deny access completely or fix that.

[m3r3lin]

I'm having the same issue

[glglgithub]

amazing! it indeed works! thanks @gerardbm

[dhruvil009]

Look at the top of the image. Coursera learners are currently experiencing trouble resetting passwords and logging in. In order to login you must follow the Captcha

[aakuptsov]

Look at the top of the image. Coursera learners are currently experiencing trouble resetting passwords and logging in. In order to login you must follow the Captcha

Taken on February 4th 2019

I saw that too. Do you think coursera-dl will work properly as soon as Coursera fixes that?

[khtang]

I tried 18 login attempts before the download started... I imagine all these retries from automated tools must be taking a toll on coursera's current login issue.

[anim070]

I think its Coursera Server Issue, i tried around 10 times then is worked!!

[ryanshrott]

@anim070 @gerardbm Tried like 50 times, no luck. Any other suggestion?

[fredharvey]

I am also experiencing this issue but despite many retries, its not working.

I have looked at the Coursera support page that others (above) have mentioned. https://learner.coursera.help/hc/en-us

I would suggest that the message across the top of the page is rather important and provides some clue that the devs need to follow up on:

"Coursera learners are currently experiencing trouble resetting passwords and logging in. In order to login you must follow the Captcha."

• what Captcha? I never see a captcha when I login?
• is something automatically providing a captcha when the Coursera login servers suspect the client is an automated client and because the coursera-dl code doesn't know about the captcha it does some action and Coursera fails the login? (in order to thwart automated downloads).
• Why would they put up a message about a captcha unless they sometimes use a captcha to prevent automated agents?

Hypothesis: Coursera has code that tries to detect automated agents and challenges them with a captcha. Humans don't typically see it but the support message is indicating that some people do and just need to use the captcha to prove they're human. Some people using Coursera-DL are able to get past the captcha trap with repeated attempts as the "automated agent detection" code by coursera is not fool proof.

@devs please help us. This isn't working. Can someone look into this?

[Update]
Ok, confirmed they are using a captcha. I logged in once and didn't get it. Immediately, logged out and tried to log back in and got prompted with captcha. From the login page.

This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply.

So how should the coursera-dl code handle this?

[constantlycoding]

If you don't mind a bit of hacking...

Login to Coursera once through the browser.

Find your installed coursera-dl site package (how?).

Modify login function in cookie.py (where?) to the following:

def login(session, username, password, class_name=None):
    session.cookies.set('CAUTH', '[YOUR CAUTH COOKIE VALUE]')

Please google how to inspect cookie values for your browser. You may get some clues here.

Run coursera-dl as per usual.

Do note that cookies expire, though it's quite long in this particular cookie's case. In case it does, do login through the browser again to get a new cookie.

[jethar]

Tried to change the cookie parameter as above. Has the AUTH_URL_V3 changed to https://www.coursera.org/api/login/v3Ssr

That is teh URl I see when inspecting in chrome.

Also the cookies does not seem to contain CAUTH token anymore. I am seeing cookies as follows -

[bv9900]

Hey all, just found coursera-dl and was surprised to see it failing. Ended up here; tried @Isaac-the-Man , @dhruvil009 , @constantlycoding , and @jethar 's solutions. None seem to work, but I'll continue poking around. Probably the same as all of you, I have all of the requirements, the correct interpreter, etc. Working on it, but would like to stay posted on this. On Debian 9, newest version.

Edit: After clearing my cookies and re-signing in, I do see the CAUTH token. Long string of alphanumeric characters, not much use for me to put it- but at least it reappears for me.

Edit 2: Interesting. Pulled a Windows user trick and repeatedly banged in the command. Got this on the ~7th try:
main@maincomp:~$ coursera-dl -u XXX@XXX -p XXX unix coursera_dl version 0.11.4 Logged in on coursera.org.

Anyone have any ideas? It logged in, so it might be server weight.

[mkstayalive]

It works with CAUTH parameter which you can get from cookies by logging into Coursera via browser. There is no need of passing username and password to the command via this method.

coursera-dl -ca 'some-ca-value-from-browser' modelthinking-004

[rayryeng]

Getting the CAUTH parameter from my cookies worked for me. The user+password combination doesn't work for me and it gives the HTTPError 400 Client error. Thanks!

[Luciano-Delaude]

I tried with CAUTH and it didnt worked, someone else has this problem?

[cahyoardhi]

I tried with CAUTH and it didnt worked, someone else has this problem?

i got that problem too, and it was fixed...
the problem was i'm install coursera-dl on conda (i think the conda version for now have some bug), i uninstall coursera-dl on conda and install it using pip, maybe you can try that

Thanks for the reply! I tried that because I also was using conda but it didnt worked, it wont let me log into coursera, don't know why

[nikhil-redij-pcln]

Instead of export all cookies you can copy only one value:

1. login coursera from your browser
2. copy CAUTH value from your cookies list. For chrome on the tab with coursera open developer tools -> application -> cookies -> https://www.coursera.org -> CAUTH
3. coursera-dl -ca 'cauth-value-copied-from-browser' modelthinking-004

I was having similar issue which was posted in #702. But this solved it :). Thank you

[rohankumar1999]

great! this works! just login into [https://learner.coursera.help/hc/en-us] and wait for a couple of minutes(I had to wait 10mins) and then later try the command..happy learning!

[nkxy007]

Create a file coursera-dl.conf in the same directory of the coursera-dl with the text below:
--username <email_here>
--password <passwd_here>
--subtitle-language en
--cauth

cauth value will be available only if you login to coursera and then check in cookies.
cauth value changes time to time, update it if errors occure.

it works

You don't need to set username and password in the config file if you have the cauth parameter

[themrcesi]

Okay, so at the beginning it didn´t work for me. I was taking the CAUTH value directly from Chrome settings. However I tried this other approach to get the CAUTH value.

1. I downloaded the cookies.txt once I logged in Coursera using this extension of Chrome.
2. I check in that file the CAUTH value.
3. I used coursera-dl -ca <CAUTH_value_of_downloaded_file> <name_of_the_course>

Hope it helps somebody! 😄

[armanism24]

Following worked for me:
use edge browser, open coursera and login. Now press F12, go on network tab, now press F5(refresh), click on coursera.org, on right side, from tabs choose cookies.
Now look for CAUTH cookie,
Copy its value. (chrome does not allow to copy the value, edge allows till writing of this post).
run command:
coursera-dl -u xxxxx@xxxxxxx -p xxxxxxxxxx --cauth ccccccccccccc course-name
here ccccccccc is the cauth cookie. Take a note that there is double -- before cauth.
Happy learning:)

@jarrettyeo hooorayyy this one did it! it was easy thanks a lot
(06/02/2020)

Hey. Thanks a lot bro. After 3 days of searching on the internet, finally found a working solution 😄
Tried using Mozilla Firefox (CAUTH values are in Storage section in Developer tools (F12) for Firefox) and it worked.

Note: If your cookie value obtained begins with a "-" (hyphen), try obtaining another one, by re-login; because that will create errors (happend to me initially)

awesome worked for me

[gowthammani]

The cauth method works. The auth value can be copied from the chrome developer options itself.

1. Goto coursera site and login first,
2. Then right click and select inspect option
3. Click on the Application, select 'Cookies' under the 'Storage' option, and select the coursera url
4. you can search for auth cookie and click on it once you find it.
5. you can the content which is shown once you click on the cookie.

[SG75]

I used the --cauth method

[ZXSwire3]

@SG75
I was having the same issue but I fixed it by using this #778 (comment)
hope it helps you :)

[axelock]

I used the AUTH method too:

1. Login to coursera.org
2. Go to Chrome / Settings / Cookies / coursera.org
3. Find CAUTH cookie, copy the ugly-long value: hAMlatdpEel2Bd5DtUKfKy8Xlzxd0xgH-KrN.......du3hQMQ4aFLComrM9lCUfJY5poFiJho1RM94fPVoNMvlNWex_A-lwt7NwZ-1MA
4. Use this in command line:
   coursera-dl -ca "hAMlatdpEel2Bd5DtUKfKy8Xlzxd0xgH-KrN.......du3hQMQ4aFLComrM9lCUfJY5poFiJho1RM94fPVoNMvlNWex_A-lwt7NwZ-1MA" python
   :)

BTW, I think our nice python program should handle the
"HTTPError: 400 Client Error: Bad Request for url: https://api.coursera.org/api/login/v3"
error as a simple authentication error, and it would be nice if the program itself would
suggest some other authentication methods.

Then it will make less confused and more satisfied users... :>

Anyway, thank you for this great tool!

[abdoaboganima]

If you are using chrome just press this link chrome://settings/cookies/detail?site=coursera.org, open the CAUTH field, copy it then paste it after -ca argument

Hello,

Same issue on Debian Buster (python 3.7) with a fresh install of coursera-dl.

I tried the two methods for downloading which raised two distinct exceptions:

• using -ca <cookie_cauth> option after beeing logged in Coursera ==> HTTPError 403 Client Error: Forbidden for url: https://api.coursera.org/api/memberships.v1?includes=cour[...etc...]nrolled
• using -u and -p options. I also tried the -n option with a .netrc file ==> requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://api.coursera.org/api/login/v3

After the command with -ca option, I am logged out from Coursera.

NOTE: I also tried to put the certificate in my coursera-dl.conf file instead of the -ca option but it still did not work (403 Client Error + logout from Coursera).

Regards,

[hasnain-ahmad]

Create a file coursera-dl.conf in the same directory of the coursera-dl with the text below:
--username <email_here>
--password <passwd_here>
--subtitle-language en
--cauth

cauth value will be available only if you login to coursera and then check in cookies.
cauth value changes time to time, update it if errors occure.

If you are using chrome just press this link chrome://settings/cookies/detail?site=coursera.org, open the CAUTH field, copy it then paste it after -ca argument

$coursera-dl -u <your-email> -p <your-password> <course name> -ca NtSNWJTmbbO0jdVuLtjF1WIFnBtpFE9nj7-vG6Nrsm6WpnwgeX0TO1YC2NRBpDwmoHCg6ip5H9RONRMLvj-v6g.9GPRA6YiOyGD3QKL2GMOBA.1wpKC3vCl1UUocFkGwPZKhAaV9U_Sop7gNGKdOhw06Eif1VwFBUuF5RshKWhLKlgOxzdNXDAmFsZBuhGOwBkDKQUpa7KWgmR7DPqYVcAICYO8fcq9SkhwF2yn6IJRN7kNBL3QheqP7Vl_nF-J4xIbxsFljsnc7OZyEZ4QbnJ6XpoMioI4nLiFpfyUgxKaM_j

Thanks this works perfectly for me

I'm commenting this two years later. Adding the argument --ca worked for me as well. Thanks!

@gerardbm how does it work for you i just tried it and it didn't work ?
i believe that that coursera changed the api it gives me the same error of 400 bad request

Error 403 Client Error:
Forbidden for url: https://api.coursera.org/api/onDemandCourseMaterials.v2/?q=slug&slug=with&includes=module

27th July 2022, This works perfectly fine with me, thank you for the great tools!

This solution used to work for me on other systems, but of late, my CAUTH cookie value got much larger (~500 characters) and that seems to break argument parsing in the script. I'm using FF on Ubuntu 22.04. Wondering if anyone else is experiencing the same. I've tried to pass both at the command line and also through the coursera.conf file.

When passing through the command line I get:

$ coursera-dl algorithms-part1 --ca my-very-long-token
usage: coursera-dl [-h] [-u USERNAME] [-p PASSWORD] [--jobs JOBS]
                   [...truncated for readability...]
coursera-dl: error: unrecognized arguments: my-very-long-token

I've had no issues with a 558 character CAUTH field on coursera-dl 0.11.5.

I can get to chrome://settings/cookies, but the full path or chrome://settings/cookies/detail dont work for me and I dont see anything site specific at chrome://settings/cookies.
