Question

Python bottle server loads and runs but fails health check

I wrote a very simple python bottle application, which responds to a POST with the data for the given user token. It runs perfectly locally, but when I deploy it as an app, it builds fine, and starts running:

[2021-09-26 19:23:50] Bottle v0.12.19 server starting up (using WSGIRefServer())... [2021-09-26 19:23:50] Listening on http://localhost:6161/ [2021-09-26 19:23:50] Hit Ctrl-C to quit.

But then hangs and fails the health check. I’ve written similar apps/components that run fine opening up listening for a websocket connection. Is there any reason why this wouldn’t work? The runtime logs tab says nothing and the Health Check only says that ’ App is running slower than expected’ is a common cause. Is there any way for me to get more info about why the Health Check fails?

Thanks.

Hey @Kiva,

From those logs it looks like your app is bound to localhost. This unfortunately won’t work in app platform. I’d recommend updating your app to listen on interface 0.0.0.0:8080 and try running that again. Running on localhost will cause the app to fail health checks.

Hope it helps! Nate
