Error message :This site is running TeamViewer

December 2016


I"m getting the following error message upon accessing a certain website:
  • "This site is running TeamViewer. Free Port 80...."


Try to change the port used by Teamviewer ...
  • Go to Options > General > Network > Proxy parameter
  • Uncheck "Use proxy" and click on configure
  • Then put your IP and port number in place of -1
  • The "Netstat-an" command will give you the list of ports occupied. From there, it is possible to determine a free port.
  • Configure the firewall and router if necessary.

Thanks to lionhell454 for this tip.
