One more tip about “How to open Firewall ports in Windows 10.”

The user should check if the firewall is blocking a specific port, or need to open a specific port when “network error” comes up.

Before you do follow this process, you can do simple test. Turn off firewall and try to use the web license. If it works, that means your firewall is blocking our port.
