Djm rec app disconneting

Hi 

I problem with djm rec app is disconnecting during recording after a few minutes. I saw a few posts with the same problems, but also I want to ask why I have this information (bottom of the screen) on the app when the app is connected or even disconected from the mixer. 

Yesterday I had this issue too but somehow after many attempts, I was able to record a mix without any problem

Thanks in advance
