Invalid HTTP upgrade when try to connect #37

Closed aytoku closed 3 years ago

aytoku commented 3 years ago

When I try to connect, I am always thrown into onDisconnect. I looked into the connect() and there I came across an error 308 and message "Invalid HTTP upgrade". Do u have any solutions ?

AFAIK, a websocket connection is established via http UPGRADE command. Check if your webserver allows WS connections.
