I have privateinternetaccess.com vpn installed.
When I open TeamViewer it says "Not ready. Please check your connection".
Turning vpn off doesn't help.
Uninstalling it helps.
Thank you for your post.
It seems like TeamViewer can't reach our servers when going thru the VPN tunnel. Please make sure your PIA(privateinternetaccess) is updated.
If that doesn't solve the problem, you might need to contact the VPN provider, and ask them to make sure "*.teamviewer.com" is not being blacklisted, and port 5938 is open for all IP's for TeamViewer.
I hope that helps!!!!
