Android apk and browser bug

Hey,

I found a weird bug on the weekend with my home bOS server.
When I tried to connect to my server with android apk I got a error: "OnCallBack: TypeError: Cannot read property 'ShowForm' of undefined"
I got this message even with chrome webrowser on android, but i could connect to other servers with my phone so the bug was only on my server... On PC i could connect to my server just fine though, only android couldnt connect.
When I restarted my phone it started to work again. I did not change anything else on the server or on the phone.

Has anyone else had this problem?
