I've seen a ton of posts about this, but no answer. I have 2 computers at home. When at home, I can connect to them. When remote, I cannot. I get the error. Disabling IPv6 isn't possible for me, so I can't try that solution. Even if that is the solution, it's clearly a problem with TeamViewer.
Is TeamViewer aware of the problem? It seems to be affecting people for months.
