I have recently made a 1.12.2 forge server for me and my friends to play on. I have been using these 2 tutorials:

I have made the server and it works locally, however I cannot connect using my public IP and neither can my friends, you have to use my ivp4 IP while on my internet to join. If I try using my public IP on my internet to join, a error message appears saying:

io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information:.`


  1. I'm on windows 7
  2. I'm not using ethernet
  3. I have a port forwarding thing
  4. My internet router is Belikn

Thanks for assisting me with my problem.

Only you must connect via IPv4. Your friends will connect with your public ip. (ie, http://www.whatsmyip.org/)

Firstly I suggest you surely check whether port 25565 is open or not.


Secondly I urge you to make sure that your firewall is not blocking any minecraft components. Usually when you open up a server, it may ask you "do you want to block stuff firewall blah blah", make sure you click no.

  • What has IPv4 to do with this? – gre_gor Mar 15 '18 at 22:04

  • the website contradicts what google says is my public IP. And the website also says my port is closed, how do i fix this? – Lordsaviorworshipmepls Mar 16 '18 at 19:38
  • Use the google one. The website says your port is closed, which means you did not port forward properly, thats why your friends couldn't join, how you fix this, well I am sure there are guides for your router youtube.com/watch?v=Ie6Np1Ys_4k – K Split X Mar 16 '18 at 21:51
