Hello. Tracker TK102B clone stopped working. It worked under IP 22.214.171.124, port 20504 and device IB-GT102. It had been working for a long time but it stopped working two weeks ago. I tasted tracker on 126.96.36.199 20504 and the packets arrived to the server but tracker is not visible on 188.8.131.52 in the application. Could you advise how to solve the problem? Thank you.
