What's your current start command?

"startCommand": "/bin/sh -c \"sh deploy_script.sh && python manage.py collectstatic --noinput && gunicorn mysite.wsgi --timeout 3000\"

The error you are getting, is that just a plain text error when making a request to your service?

No. When I click on a URL on my app, the app becomes unresponsive and after a while shows a stream timeout message.
I have to restart the app to be able to access it again

You meant to answer yes to my question.

Has your service ever worked before or is this an error you are getting recently?

This happened about 15 days ago

So you are able to restore access when this happens by restarting the service?

yes. This often happens after I deploy new code

How long after deploying new code would you get this error.

about 1 min after deploying new code

Does it work as intended up until that minute mark?

sure

Its more of a yes or no type of question, I'm sorry but "sure" doesn't answer the question sufficiently.

Does your deployment work as intended up until that minute mark?

yes

How long will the deployment work for after you do a restart?

about 2 min and now after rebooting, my application cannot be accessed.

my application cannot be accessed.

I'm sorry but that doesn't provide enough information.

What information do you need?

Please go into more details.

Here is screenshot error log:

There's no errors there.

From the information you have provided all signs are currently pointing to an issue with your app / code / config itself, as seems to be exiting, softlocking, or crashing.

Are there any errors in the logs or do your metrics look strange?
