The websocket connection does not work

1

Hello.
My code worked on Heroku, where nginx stood in front of my application as a reverse proxy server and a simple setup made connection possible:
map $http_upgrade $connection_upgrade {
default upgrade;
‘’ close;
}

Now it has become impossible to connect to my websocket service.
Apparently the server "onrender.com " does not respond with the necessary headers for the upgrade connection.
Is this related to the limitations of the free plan?

Hey,

Sorry for the late reply!

Do you have any error messages we could look at?
