Sign In doesn't work unless that I restart teamviewer

Hello, 

I have this issue for 2 month that is still happening and it's start to be really annoying. 

No matter what I do, after a few minutes that I didn't use my teamviewer my user is logout and I can't sign in again unless that I restart the Teamviewer application. 

Is there any fix for this? Because it start to be really annoying and I lose productivity.
