Question
Constantly Running Python Scripts on App Platform

Asked by Amila Deshan
Hi,
I have a Python script that I want to deploy as an app on DigitalOcean. I already created that script in the APP Platform App. Then the app platform url is going to use as a Websocket. After 5 minutes, I can see my an error message saying " Connection Closed". Because of that my front end which is connected to the websocket has an issue saying “Websocket Connection Closed”.
Because of the connection closed after 5 minutes, I can’t do anything with my websocket. Can anyone please help me to understand how to make my app to run 247365 constantly. I have assigned a custom domain to my app as well.
This is the app run command
uvicorn main:app --host 0.0.0.0 --port 8080 --timeout-keep-alive 300000 --ws-ping-interval 30 --ws-ping-timeout 30
This is an urgent matter. Please help me anyone asap.
Thank you.

Heya, @amiladeshan
When defining the WebSocket server (
uvicornin your case), you specify the internal port (e.g., 8080). However, externally, App Platform exposes your app on port 443 (via HTTPS). The platform handles the mapping between the internal port and external HTTPS endpoint.A similar question was asked before in the community:

You do not need to reference the internal port in your WebSocket client. Simply use the domain assigned by App Platform.
