Is it resolved? if yes please share the workaround.

Facing the same issue.

 

Log /var/log/ts/bd.log:

websocket.c:0266|101 Switching Protocols HTTP status arrived, but the websocket hanshake failed.

websocket.c:0267|Possible reasons are websocket profile isn't assigned on a virtual server or handshake is illegal.

 

applies websocket profile but, not resolved.
