WebSockets and the HTTP CONNECT method convert the connection through the HTTP filter into pass-through mode. However, if OneConnect is enabled, then the BIG-IP system disconnects from the server at the end of the tunnel handshake, thwarting this.
No tunnels can be made if OneConnect is enabled, breaking WebSockets.
This occurs when a OneConnect profile is attached to a HTTP virtual, and the client/server tries to open a tunnel via the CONNECT method, or via the WebSockets 101 Switching Protocols status code.
Disable OneConnect. This also can be done within an iRule by using ONECONNECT::reuse disable.
WebSockets and the HTTP CONNECT method now work with OneConnect.
