cypress run times out waiting for the browser to connect #3310

achelonmm · 2019-02-04T10:04:15Z

Current behavior:

I have an automated release for my test suite. It consists of 8 specs that are executed one after the other.

A few weeks back, one of the specs got stuck and I had to force a shutdown of the release. After that, on every release, after the first spec is run, Cypress fails to open the browser or find it or something and the tests fail.

This is the error I'm getting:

2019-02-04T02:11:09.1221261Z Timed out waiting for the browser to connect. Retrying...
2019-02-04T02:11:39.1105823Z 
2019-02-04T02:11:39.4465327Z Timed out waiting for the browser to connect. Retrying again...
2019-02-04T02:12:09.4535443Z 
2019-02-04T02:12:10.1352111Z The browser never connected. Something is wrong. The tests cannot run. Aborting...

I have deleted the Virtual Machine I use for the test and created it again, changed versions of Chrome, changed versions of Cypress and nothing changes.
If I enter the VM with the release user, and use the command manually on a command line, it works, but in the automated release doesn't.

I'm currently out of ideas.

Desired behavior:

Every spec should run correctly as it did before

Versions

Cypress 3.1.4 and 3.1.5
Chrome 72.0.3626
VSTS for release automation

Is there any way to clear the App Data or maybe uninstall / reinstall Cypress altogether?

Is there any way to clear the App Data or maybe uninstall / reinstall Cypress altogether?

We did. We uninstalled and reinstalled and then uninstalled again and installed previous version.
After that we uninstalled and reinstalled.
We even deleted the VM and created it again new, and nothing changed.

Are these tests able to run when opened in Electron locally?

Could you provide the test code - for spec 1 + spec 2?

Likely something changed a few weeks ago that is causing this.

If I run them locally, they open both in Electron and in Chrome.
In fact, if I enter the VM and run the same command manually it works.

The weird thing is that it doesn't seem to be related to the spec as I tried changing them (order and so) and it didn't change a thing.
First spec always executes perfectly, second one can't open browser anymore.

Apart from that, the only thing we do is log in:

it('TC1317 - Check that login works', function () {
    cy.visit('')

    cy.get('#btnLoginOauth')
        .click()

    cy.get("#dniField")
        .type(Cypress.env('user'),{force:true})

    cy.get("#passwordField")
        .type(Cypress.env('pwd'),{force:true})

    cy.get("#btnLogin")
        .click()
    
    cy.wait(5000)
})

Perhaps try to collect some more logging information during cypress run https://on.cypress.io/debugging#Print-DEBUG-logs

jennifer-shehane · 2019-02-22T07:55:55Z

You may also want to be aware of this issue - where the click does not execute in after hooks if a test fails: #2831 but I don't think this is related to your problem.

achelonmm · 2019-02-22T08:15:08Z

Yeah, I've been dealing with this too, but it's not related to my problem as the first spec, which in my case just tries to log in, log out and make an incorrect login, works perfectly and it closes the browser.
And the next spec doesn't even do a click because the browser never opens.

I'm checking 2831 anyway, thanks!

Will try to DEBUG and get extra information.

Just a set DEBUG=cypress:* would work or is it better to go for set DEBUG=cypress:launcher?

achelonmm · 2019-02-25T08:14:31Z

Hello,

I have tried using DEBUG=cypress:*, however, didn't get any additional information, as the logs do not include the debugging information in the console, and if I execute everything manually, it works perfectly.

Any other idea or workaround? Is there a way to log in a file everything printed by DEBUG=cypress:*?

jennifer-shehane · 2019-02-25T19:31:50Z

I think you're going to have to try to narrow down the test code base to find the core issue. So, cut out half of test code, does it still fail. Try half of that code, etc until you get it to the smallest amount of code to run to reproduce.

@bahmutov - you have any leads or suggestions? I know you worked with VSTS some.

devsh4 · 2019-03-06T18:15:44Z

@jennifer-shehane I face the same issue (intermittently). With cypress version 3.1.5. For earlier versions it use to work just fine.

Running my test suite locally using npx cypress run (Electron 59) sometimes works and sometimes it doesn't and fails before running the first test.

Moin-A · 2019-03-24T06:04:39Z

I too got the same error, the first two specs are running properly, However from the third spec onwards I am gettin the error :

devsh4 · 2019-03-25T18:36:42Z

I found the cause of that issue. It seems like while starting, cypress threw an error which didn't allow the headless browser to fetch the URL (baseUrl in cypress.json) because the base URL had auth credentials and there were a couple of other URL's mentioned under env (which were cross domain) which my tests needed to access. This was the primary issue.

Removed baseUrl altogether and I created a variable under 'env' (for all the URL's) and then it worked fine. Looks like there is CORS related bug, where cypress cannot connect to electron while reading the baseUrl value from cypress.json which further has multiple urls (cross-domain) mentioned elsewhere in the same file.

jennifer-shehane · 2019-04-18T07:59:06Z

@devsh4 See this issue - it is what you are describing #1598

Pavel-Husakouski · 2019-05-16T12:44:53Z

I have the very same issue. Cypress version 3.1.0. There is no auth credential in the baseUrl. Cypress fails from time to time, about one of 10 times is failed.

cbernardes · 2019-07-18T01:25:40Z

Thanks @jennifer-shehane for trying to support, but I am having the same issue and all the suggestions implies try-error attempt. Here is the log I have:

We encountered an unexpected error talking to our servers.
Because you passed the --parallel flag, this run cannot proceed because it requires a valid response from our servers.
The --group flag you passed was: web
The --ciBuildId flag you passed was: 3082
The server's response was:
StatusCodeError: 503
{
  "error": "timed out creating run"
}

and it looks like a failure of cypress to orchestrate parallel request or even allocate diff servers/machines to it.

jbpallingayan · 2019-09-03T06:07:12Z

Were experiencing this right now. Is there any fix for this?

cbernardes · 2019-10-11T02:34:56Z

There is a workout around to fix this problem. You can overwrite their values reseting the env variable API_RETRY_INTERVALS. In my case I added to my CI/CD pipeline the following configuration:

Name: API_RETRY_INTERVALS
Value: 5000,5000,5000,10000,5000,5000,5000,10000

It means the Cypress will retry every 5 seconds 3 times, then 10 seconds and so on. The number of retries are exactly the length of your value list.

Pavel-Husakouski · 2019-10-11T13:28:34Z

Looks like headless electron works without that issue. @cbernardes Could you explain that magic ?

cbernardes · 2019-10-14T04:08:24Z

Hey @Pavel-Husakouski it is not magic. It is just the way they have built, I hope intentionally, their middleware. In my case it was hanging-out on the first try only, but it was enough to delay my CI/CD. After digging through their code I found this solution :D.

#openSource <3.

Pavel-Husakouski · 2019-10-14T10:11:16Z

Actually, all our tests are failed because of this issue. Cypress tries to connect per every test and fails - about twenty times "The browser never connected. Something is wrong. The tests cannot run. Aborting..."
We switched to headless electron because looks like it works a bit better. However, I don't have enough statistic to make any serious judgement.

cbernardes · 2019-10-14T10:47:50Z

@Pavel-Husakouski this is only necessary when you run your tests in parallel. This request is exactly to know which suite to pull from the queue. Said so, I would strongly encourage you to run your CI/CD with electron.
If this is happening when you are running your tests locally, I would say you are having the wrong approach. They have a very good dashboard to help you with your tests execution and this don't require the API request which triggers the error referenced in this page issue.

GettinDatFoShow · 2020-01-09T16:36:33Z

I was experiencing this error while using angular cli for the server and the electron browser. I think the problem was that the live-reload server was trying to reload the application during the process of the cypress testing. When I serverd the code with these flags: ng serve --liveReload=false --watch=false, then it worked perfectly. Hopefully this helps some.

Pavel-Husakouski · 2020-01-10T10:24:56Z

I think the problem was that the live-reload server was trying to reload the application during the process of the cypress testing. When I served the code with these flags: ng serve --liveReload=false --watch=false, then it worked perfectly. Hopefully this helps some.

That's interesting. However, we don't use any live reload under Cypress. Moreover, we face the issue under the production environment. Anyway, electron works much better.

mingyixu · 2020-02-09T01:15:27Z

I too got the same error on cypress 4.1.0, auto execution, I run CI/CD with electron, but 10% can got this error.

suresh-cg · 2020-02-19T16:46:38Z

We are also facing same issue , the fist spec execution is passed and remaining spec file execution status results in failure due to time out issue.continuous failure in headless and test runner too.unable to invoke the electron browser from second spec execution.Tried out with all specified options ,it's invain.

Issue can be reproducible with cypress 3.4.1 ,3.8.3 as well as v4.0.0 on electron .
Looking forward for further resolution .

mdorda · 2020-04-03T12:21:52Z

Same issue here. Everything works like a charm on MacOS, but on our system server with Debian Stretch, google-chrome-stable 79, node 12.16.1 and npm 6.14.4 it does not work. It is 100% cypress error, because I tried the following versions:

4.3.0 - the error occured, browser is not connected
4.2.0 - the error occured, browser is not connected
4.1.0 - the error occured, browser is not connected
4.0.2 - the error occured, browser is not connected
4.0.1 - the error occured, browser is not connected
4.0.0 - the error occured, browser is not connected
3.8.3 - works!

dawid-bobowski · 2022-06-10T11:31:44Z

Any progress on that? I have the same issue with Cypress 8.3.0 on Jenkins.

OndeVai · 2022-07-07T21:20:08Z

damonhnz · 2022-07-20T02:44:41Z

I was having this issue about 50% of the time running on a mac (but not at all on Linux) using Cypress 10.3 and Electron browser. Disabling the GPU has fixed it for me.

export ELECTRON_EXTRA_LAUNCH_ARGS=disable-gpu

testingtrail · 2022-09-27T02:00:53Z

Github Actions
cypress/browsers:node12.18.0-chrome83-ff77
"cypress": "^9.5.1"

I am running github actions, and In my case I changed some files from This.js to this.js and when committing to Github the files were not changed to lowercase which other cypress files were calling as import base from './this'; so I manually changed the files in the git repository to be lowercase, and then my workflow worked. It may be silly things like these that cause those errors.

raghavharness · 2023-04-07T09:04:20Z

We were facing same issue with cypress 12.5.0 and Electron 106. The issue for us was coming from XDG_CONFIG_HOME env variable. It was not getting set and it seems this gets used by electron. We tried to set it manually XDG_CONFIG_HOME=$HOME/.config and things started working correctly. Sharing here if it helps anyone.

w4dd325 · 2023-04-26T10:36:57Z

My anti-virus was causing this issue for me. Once I disabled it, the issue stopped.

warrensplayer · 2023-04-27T19:53:47Z

Thanks for the feedback and ideas for how you were able to solve this type of issue. If anyone comes across this issue again. Please file a new issue and include a reproduction. Thanks!

matheuspellegrini · 2023-07-04T15:21:43Z

I've faced this same issue and after a long research I've identified that my problem is related to webpack build, so I've tried to build(npm run build) and my webpack run out of memory(WSL), I've 32GB of RAM and this still happends, so I just run this export NODE_OPTIONS=--max_old_space_size=8192 and cypress work again, took me some months to discover this as cypress doesn't stop or show errors related to webpack build(just when succeed). Hope I can help you(I've never found that related solution).

We are also experienced that.

We were running builds on Azure DevOps on prem agent (docker based) with Cypress 13.1 and Electron -> Works ✅
Then we switched to a scalable cloud agent with Cypress 13.1 and Electron -> failes with the mentioned error ❌
Then I switched from Electron to Chrome and it works -> ✅

Very weird... I tried debugging and changing from localhost to 127.0.0.1 / 0.0.0.0 on cypress and dev server side but with no luck.
