I used to play via hamachi, but for some personal reasons i cant do it anymore. I am trying to set up a server for AGES, reading tutorials and searching forums. Here is what i did:

1 - Donload the "minecraft_server.1.8.9.jar"

2 - run it and Change EULA

3 - put my external IP on the "server.properties" (just how i used to do with the hamachi ip)

4 - start the "minecraft_server.1.8.9.jar" again

5 - it immediately closes itself for some reason.

When i put my local IP on the "server.properties" the server keep it up, but noone can connect ofc...

I have done the Port foward thing and disabled windows firewall. Even so, when i test the port, it says its still closed somehow. Could this cause the server to immediately close?

All help is welcome, i am desperated.
