TeamViewer: Not ready. Please check your connection

TeamViewer proved to be a nice piece of software every now and then.

Have been using it since version 5 and up to it’s latest v12 incarnation, on systems spanning from Linux, OSX and of course Windows.

This morning thou, on a Windows 7 64bit system, the v12 of TeamViewer (which has been up and happy for like forever) refused to SignIn with it’s back-end; the error:

Not ready. Please check your connection.

It just kept throwing this message whatever I was doing:

  • reset the system
  • uninstall and reinstall
  • disable the Antivirus (Webroot secure Anywhere)

One think did help but I’m not happy about it:

  • turning off the system’s Firewall
