Symptoms

WebSocket connection wss://farm_url failed: Connection closed before receiving a handshake response

Cause

Required protocols and settings are being blocked/misconfigured in the software/hardware firewall and/or the Load Balancing solution in use.

Resolution

The filtering rules and settings, responsible for the WebSockets must be enabled on the Firewall in use.

Parallels RAS HTML5 using  the following protocols: WS, WSS, HTTP/1.1

NOTE: Using WS does not mean that a connection is not secure. RAS HTML5 always redirects WS/HTTP to WSS/HTTPS.
