Resolving the Port 80 Conflict on Windows Systems Running Skype

From time to time, a new user will install DesktopServer on a Windows-based PC and run into an error message about another service running on Port 80. Port 80 is required for any local development environment to work, so when something else is utilizing this port, DesktopServer will not install correctly.

Many times, this issue is caused by Skype taking over control of Port 80 in order to make it accessible to people behind corporate firewalls. Also, it sometimes happens that once you have upgraded your Skype, you will find that your locally installed websites only display a white screen. This is also caused by the Port 80 conflict. (An easy way to tell if your white screen is caused by a Port 80 conflict is if you also get a white screen when you click on the “Sites” button on the main menu of DesktopServer.)

How to Resolve the Port 80 Conflict Error

  1. Open Skype (if it has not already been launched.)
  2. Go to Tools > Options from the dropdown menu.
  3. Select “Advanced” in the left-hand column, last option.
  4. Select “Connection”.
  5. Deselect the option that says, “Use port 80 and 443 as alternatives for incoming connections.”
  6. Click Save.
  7. Exit and then restart Skype.

That’s it! You should now be able to complete your installation of DesktopServer
