According to my research the issue seems to be of no specific cause, thus there is no firm answer for that, However I made some changes in order to detect connection and disconnection and do some following actions after that. Also I have added the error throwing because previously If the action failed user wouldn't be noticed about that.

Dev log : JS channel has been updated in order to support throwing errors

@SanghamitraBhowmick1993 Plz try again and see If you seet these imrpovements:

1. You should get proper error message if connection didn't happen
2. Connection error should happen less than before however there is a possibility that the hapening doesn't change, If that is the case I need the senarios in which this fail happen.

The error seems to have no solutions, I will add a mechanism to retry till to some number If It fails.
