Port not opening?

Question

Hello, i am relatively new to Unity, so hopefully this is not a dumb question. I am using this to create a server on the client:

Network.InitializeServer(32, 25001, !Network.HavePublicAddress());

For some reason when i go to an online port checker, and i type in port 25001, i get an error saying it is closed. This also is why my server can not be seen on the master server...I think. All examples i follow lead to the same issue.

The server is registered, but i do not get that the server is online. Why is the port not opening? I have disabled my firewall and port-forwarded port 25001.

Also, could i use a linux server (with no UI) to run a game server?

Actually, for some reason, when i added Network.InitializeSecurity();

before it, it worked.

This is not working for me, the port still closed, but if I run an HTTP server on the same port, the port is open and I can access from internet.

@Agnostic:
Are you sure that the port isn't used by a different application? Every port on a PC can only be used by one application at a time.

Some things you might want to check:

Can you connect locally to your server when using localhost / 127.0.0.1?
If you can, it's most likely a router / firewall problem. If you can't the server somehow can't be started or it's blocked by your firewall.
The HTTP uses TCP while Unity / Raknet uses UDP. Make sure you port-forwarded the correct protocol. In most cases you simply forward both.
I know that some routers do not allow local loopback connections. That means the whole world can connect to you, but you can't connect to yourself. That's extremely annoying (i know that because my ISP gave me such a router...) but you can't do anything about that besides using a different router.

Is your Port Forward placed on Right IP of the router? otherwise it will still block

Instead of using port 25001 try to use 127.0.0.1

That is an IP address NOT a port...
