WebSocket connection establishment timeout
WebSocket.*connection.*timeout|ws.*open.*timed out
Fixes
- 1.Increase connection timeout: set a setTimeout on the 'open' event and close if not received
- 2.Check network path — firewalls or corporate proxies may block WebSocket upgrade requests
- 3.Try wss:// (port 443) which is less likely to be blocked than ws:// on non-standard ports
