Several Problems with Q5

[icerno78]

Hello everybody.
All started with the Password Change for my Google account. Suddenly i had no more Access from my himedia q5 box to Google pla store and YouTube. I deleted the account and nothing changed. Then i found the hint in this Forum to deinstall the play store. After that i updated himself and i could enter my new Password.

But then it got really frustraiting. I started Kodi and and it was updated from 16.x to 17.6....
My remote Control (Yatse) is not worling any more, because i cant find the Settings for "zeroconf" in the kodi menu.
HIControl app on my Phone and tablet cant find the q5 box anymore. But the box is connected and can Play Video files from my nas.

So any adive how i can get the HIControl App and my remote Control to work again?
