Fix the issue -- 3

I have one android application which is a live quiz app and this app was created with Kotlin.

I have a live quiz mobile android application and this was created with Kotlin. Also, the app has a backend. We were used the below technologies for the backend side :

1)Nest js



4)[login to view URL]




But sometimes the application throwing an internal server error so we need to fix that. The error looks regarding connect the socket or something like that. For this, I need someone to test the app with a large population(so you need to know how you can test the app) and find and fix the problem.

If you are able to fix that issue please contact me. Don't send me copy-paste proposal please.
