WebSocket connection issue (Handshake failed)

Hi jitsi team,

We’ve been seeing handshake failure when some users tried to connect to the signaling server via websocket. This seems only happen on certain devices, mainly android devices. Retry won’t help. Maybe relate to the certificate setting on those devices. Did you see similar issue with your deployment? Any thoughts?
