Hi @cbr7 I'm not able to reproduce the problem.

I have tested on Mac, with two versions AI Lab 1.3.0 and with the main branch, and with Podman Desktop main branch.

If you still can reproduce it, could you please share the exact versions of Podman Desktop and AI Lab, and the information of the underlying container (its state, its logs, etc)?

@feloy will try to reproduce after the release is finished

@feloy I've been able to reproduce it with the latest AI Lab release 1.3.2 using PD 1.14.1 release, for me it happens exactly as described in the initial report, after doing a START -> STOP -> START cycle, upon the second startup the app takes a very long time to initialize, to be clear in the end the app will work, you just have to wait for it an unspecified amount of time, currently I'm noticing around 2-3 minutes of wait time until the app is actually usable.

There is nothing inthe container/pod logs that jumped out at me when I looked.

When the app is restarted, the app's home page is accessible with curl, but is not with the browser (it seems that the browser can access it if we completely stop and restart the browser app)

Not sure what can be the root cause of the problem, opening containers/ai-lab-recipes#812 on AI Lab Recipes to have some feedback from app's developers
