Its working now after a donwtime of around 30 mins.

Hello,

We did not experience any issues during this time period.

I can see from your deploy logs that your app was constantly throwing stack traces, and the 502 status code was returned because your application did not accept the incoming traffic.

I would recommend adding better error handling and more verbose logging so that you can pinpoint the application level issue next time your app throws stack traces and stops accepting incoming traffic.

Hi, Thanks for responding.

When I checked the logs that time, I saw API requests were not reaching to the app, and I did not see any error in the logs as well.

Hello,

If your app was already in a state where it wasn't responding to incoming traffic it would be unlikely to be healthy enough to print logs, I was suggesting to add verbose logging and better error handling so you can catch application level errors before they end up soft locking your application.

Not completly sure if this was from app side, because I tried restarting and redeploying the app, still it did not work. And after sometime it started working suddenly.

Yep completely application level, if the application does not respond to the incoming request our proxy will return 502.
