Check your Internet connection or Proxy settings if you have. I also encountered this problem, and as checking, the firewall appliance block the ports of connection of team viewer. We configured the internet proxy settings of the machine with no blocking of ports or sites.

It could be possibly blocked the ports that you are using in Team Viewer. Use a connection with open ports to all or the ports you need for Teamviewer is open.

Seems like the message is from your Internet explorer browser protection component from SEP

try to remove the add-on and check the connectivity
