Local Appliance 443 Port Occupied

Scenario

After installation of  Local Appliance, the Internet browser application tries to load ‘Local Appliance’ web page but instead displays an error:

Confirmation

The Local Appliance includes the web server which typically uses port 443 (HTTPS) for communication. There can be a possibility that some other application uses port 443 for listening. In this case the port 443 is busy and web server is unable to launch.

You may have to check it by running Resource Monitor (resmon.exe). You perform it directly from Start menu or by launching from Task Manager’s Performance tab.

Open Network tab, locate Listening Ports in the bottom (you may have to expand  it to reveal its contents). Click on Port column to sort by it, and try to locate port 443.

If there is some process listening on port 443, you may have to manage out what application this process belongs to, and then reconfigure or uninstall it. If the process is Skype.exe, read the following section to know how to solve the problem with Skype.

Solution

The common problem with occupied port 443 on consumer desktop OS is Skype. This application uses standard TCP 80 (HTTP) and 443 (HTTPS) ports for additional incoming connections. You may have to change this behavior.

Switch to Skype, open Tools menu and choose Options or Connection Options:

Open Advanced tab-> Connection. Untick the “Use port 80 and 443 for additional incoming connections” checkbox, and then press Save button. After this, you have to restart Skype.

Quit Skype by right clicking the Skype icon in system tray and select Quit, then start Skype again.

After you resolve the problem with port 443 occupied, you need to remove Local Appliance via Programs and Features in Control Panel and run the installer once again.
