Getting error while using ReverseProxy

[frozenade]

Hi
I got this error message (browser's console) while using ReverseProxy. I think it's about domain binding problem.

(index):281 WebSocket connection to 'wss://somedomain.com/ws' failed:
(index):297 WebSocket error: Event {isTrusted: true, type: 'error', target: WebSocket, currentTarget: WebSocket, eventPhase: 2, …}

How to solve this?
Thanks in advance.
