Can't login to Teamviewer - Can't ping teamviewer.com

I cant login to the Teamviewer program on a Windows 10 machine. I keep getting an error "Sign In Request failed! The server did not respond. Please try again." I have used this program for years and this just started happening 2 weeks ago.

I tried putting an exlcusion in Bitdefender and also turned it off all together. It had already been allowed through the firewall. I also can't ping the teamviewer.com wesbite from this computer. Not sure if they have that turned off though. Any ideas?
