title: TcpTestSucceeded: False cannot connect to specific port
body: <p>I am trying to connect to open up port 89 on my Windows machine so others can access it, but I'm having trouble doing so. I added a rule to Firewall to allow access to port 89, but it still seems like it's not working. Any advice on how to resolve or even how to debug?</p>
