Jisti Meet Android works fine if Jitsi Data/Cache is cleared

Hi,

I have made a Jisti Meet custom server. Lately I tried from Android (fresh installation) everything have worked fine. The problem occur when I tried to access 2-3 days later where the Jisti android cannot access the server anymore. It would be worked if I clear Jisti application Data/Cache in device Setting. Then just to make sure I also tried to install a fresh new instalation in different android device and it works fine. I have no clue how to solve it, please help.
note : work fine in iOS and windows.
