When I setup Teamviewer on my Ubuntu 16.04 for the first time, I got problem. It always tell me incorrect password even the password is correct. I setup password in option, still same. and it's making random errors, slow to connect, and denied connection.
Then I decided to clean install Ubuntu 16.04. TeamViewer worked perfectly for a while. Now all of sudden the problem come back with 3 random errors, Incorrect password, slow to connect, and connection denied.
I can remote my Windows computer from Ubuntu just fine, not remoting Ubuntu computer with Windows computer
I don't understand why 
Here is log
