Huawei P8 lite - endless "Please wait while connecting"

[Hral]

Hello,

I use TeamViewer for while for PC to PC connections. Now I want to use the Teamviewer APP but only for LAN connections.

If I disable LAN connections and use a ID it works fine. But if I set LAN to accept exclusivly I have to wait for hours after my password was accepted. I get a message "Please wait while connecting" but nothing happend.

I tried Teamviewer Host won't accept LAN connections but it doesn't help.

Where is my problem?

Regards

Hral
