Server disconnected without sending a response

Hi !

Once again thanks for the amazing work on this component. I've recently added a new Axis camera in my setup and I get the following error in HA:

Everything seems to work fine though.

Thanks for your help,

Hi,

I'm also facing the same error. What is the cause of this?

Thanks

Something on server side it seems so I have no idea without more details

Hi, what is considered server side? Yesterday i tried to send you an email through pypi but I got an error saying the email doesn't exist.
Here is an excerpt of that email

"The application consists of capturing a frame, process it and move the camera a certain angle to the right or up. This process should happen indefinetely.
Currently I have na AXIS camara and a python script that sends and receives commands to/from camara.
Everything works fine for few hours of script running, but after some time the following error appears.
"

The "error" is what is in the comment above.

Regards

[Kane610]

In this context it's the camera which is the server

Yesterday i tried to send you an email through pypi but I got an error saying the email doesn't exist.

Yes I want communication to be in one place and that is github :)

Ok, makes sense :)

Do you have any idea why that error appears after some time of system working? Is it possible that the login session on the camera, expires?

Many thanks!

I have no idea. But I should add some kind of retry mechanism if request fails

I forgot to mention, I'm using your axis repository in a company project. The idea is to have the camera working 24/7. What is your availability to study this issue? This issue can be critical for the project.

Your help is very appreciated. Just tell me what you need to understand better the issue.

Thank you

[Kane610]

Right now I'm traveling. There are some rewrites I want to do of the library to help improve overall design and functionality. I plan to come back to work on this project in the not too distant future (as I have many different things going on)

[Pedro-Leitek]

Hi, do you have any news? Did you try to study this issue?

[Kane610]

Hi, do you have any news? Did you try to study this issue?

No. Still busy on other projects.

[Kane610]

Hi, do you have any news? Did you try to study this issue?

I was thinking, maybe we can do something unofficial for your case if you still need it, I don't need to publish a real release since you're running your own stuff. Does that sound ok?

[Pedro-Leitek]

Hi,
I was able to solve my issue. Instead of using your repository, I'm using directly the axis API. I think for my project and the way I wanted to do, your repository is not compatible. Thank you anyway!
