App Platform, after changing the app spec and changing it back 504 gateway error on page.

I tested changing the app spec to Ubuntu 22 then removed that change and since then my app gets a 504 timeout error. Nothing else has changed and as far as I can tell everything was put back to the way it was. Deployment goes live and is “successful”. I can’t reach the console either nor the app health check works. Anyone run into something similar?

Accepted Answer

So there was an error that for some reason started happening. In the build logs I found this:

Failed to find attribute ‘app’ in ‘app’.

After some research it appears to be related to how my Flask app is layed out. root/ -app/ –

Changing the app spec from: run_command: gunicorn --worker-tmp-dir /dev/shm --config app:app

To: run_command: gunicorn --worker-tmp-dir /dev/shm --config myapp:app

Fixed my issue. I hope this helps others.
