Make sure UDP ports open on your server or firewall [31000 - 32000] by default. As you can see from logs it is STUN timeout error. Android device can't send or receive STUN UDP packets. You can also check connection with our demo server wss://demo.flashphoner.com:8443

Hello, firewall is already off on server side and UDP ports are also open.

This issue occur when android is doing connect/reconnect multiple times. probably on the 6th-10th try.
Also to note, we are currently android is using ws to connect to server , not wss, will this thing matter on this ?
