Websockets not working on azure app service

I have been using websockets in my application and everything works fine locally, after dockerizing too.

But after I have deployed the app to azure, I see that the websocket connection is failing:

page-e3e051ef4d840b60.js:1 WebSocket connection to 'wss://<custome_name>.azurewebsites.net/backend/ws/<route_name>

whereas the same thing worked when I ran in on localhost instead of azurewebsites.

Also, in the configuration section of app service I am unable to see an option to enable websockets. Unable to diagnose this problem. I am currently on the Basic 3 (B3) plan, not free-tier.

Hope I get a fix soon.

Thank you,

Ritesh

    azure app service has stopped showing the websocket configuration question when its enabled by default. if you are using azure front door, it does not support websockets. also your internal firewalls may not support websockets. if you are using azure front door, then you need to use azure signal/r to get websocket support.
