I use Chrome in Android device to join video meeting. When WiFi was on, all was ok. But when I turned off WiFi, and turned on 3G, and access again the error "ERR_TUNNEL_CONNECTION_FAILED" occured.
I think you have to go to www.jitsi.org for an answe to this problem
The issue was gone when I used another SIM number. Don't know why.
