TV 13 - Connect timed out to ping3.teamviewer.com:5938

For the pass 2 days, TV13 could not Logon even when Internet is available.

Log fiile shows "Connect timed out to ping3.teamviewer.com:5938" and 

":Failed to connect to ping3.teamviewer.com port 443: Timed out"

It does not allow me to Login In..

TV13 is working fine in my office but not home pc.

I just renewed for the TV12 to TV13 subscription.

Thanks.
