I've been using this flawlessly for 2 months between two residences and all of a sudden can't connect from one yesterday.   A CONNECTION COULD NOT BE ESTABLISHED.  PARTNER COULD NOT BE CONTACTED AT THE GIVEN NETWORK ADDRESS.   Windows 10 on Partner system.  No changes, system worked the day before fine.   Help please. Thank you

I have the exact same issue.  But I did have a Windows update shortly before this started.  TeamViewer worked fine until then.  I'm on TV 11.  I've tried uninstalling/reinstalling, modifying firewall settings, etc.  Nothing worked.  I cannot establish an outbound connection, nor can I connect remotely to the affected computer.
