Server cannot send messages through websocket connection after 5 minutes

I have a Node.js app deployed through App Platform using a custom Dockerfile and I am using as a standalone server to support websocket. Locally it’s working fine with a system of ping-pong system to keep the connective alive. In production, it’s also working fine the connection between the client and the server is kept but when the server is not able to send any message after 5 minutes.

Is there any limitations I am not aware of? I tried to look for Cloudflare possible issues, it may be there but I am not sure.

This is quite interesting, what I usually do is to follow the steps here on how to deploy an app using Websockets to the DigitalOcean App Platform:

It seems like your GitHub repository is not public, if you make it public I will be happy to try and deploy the project and further look into what might be going on!
