I am using Teamviewer 12 on Ubuntu 16.04 , while connecting to some of the host machines running same version of Teamviewer , I get "A connection could not be established. Reason unknown" error.
This is shown even after many a attempts and when both the machines i.e. host machine and mine have been restarted.
Please note that I am able to connect to other machines running Teamview 12!
Looking forward to a solution.
Thanks in advance
