When you’re playing on a multiplayer server and you get an invalid IP address or port number connection refused error you’ll need to go into your router/modem settings. 

Go in search of something like port forwarding/port triggering / virtual servers / virtual services on your router/modem settings. 

You will see several apps listed (e.g., Minecraft, TeamViewer, etc.). Try adding an exception for each one as needed. You will probably have to restart your computer afterward. 

If that doesn’t work try resetting everything back to the default setting under admin configuration. Then try rebooting all devices including modem/router for at least 5 minutes before trying again so any cached entries are cleared from memory.

  • Check for Port Forwarding/Filtering. 
  • If that doesn’t work try: Update Java software or Add Exception in Firewall For Minecraft Servers. 
  • If that still doesn’t work make sure you aren’t using a proxy by using Add The IP Address And Port.

2. Rule out port forwarding or firewall

Sometimes there’s no problem with your Minecraft server. Instead, there may be a problem with a router or firewall that’s between you and your home network. 

  • Try port forwarding these ports: 25565 if using both TCP and UDP or just 25565 if using UDP. 
  • Test it out from another computer on your network. If things work from another computer but not from yours, then you need to check your router/firewall settings.

3. Updating your java

Updating java is a simple fix for most connection issues. Even if you don’t see any errors regarding java in your log files, running a quick java update might be all you need to get back on track. 

  • To update your java software type: Sudo apt-get installs oracle-java8-installer into a terminal window.

4. Adding an exception in the firewall

Another possible reason for being unable to connect could be a firewall blocking your connection. If you’re not sure what type of firewall you have. 

  • The first thing you need to do when attempting to add an exception for your Minecraft server. If applicable is open up your firewall. 
  • To do so, click on Start and then Run.

5. Reconfigure your network configurations

Resetting your network configurations may seem like a dramatic approach for solving a problem, but there’s nothing wrong with being extreme when dealing with network connectivity. 

It’s also not as difficult as you might think just hit up your command prompt Windows or open terminal (Mac). 

After that, type ipconfig /release, then ipconfig /renew. This will restart your computer and release all of your current IP addresses on your Ethernet card.

6. Run the command prompt

  • If you’re using Windows 7 or earlier, open up your Start menu and search for cmd. 
  • If you have Windows 8 or later, click your start button and search for CMD. 
  • A black window with a white command prompt should pop up. Type in ipconfig /all without quotation marks into that window and hit enter on your keyboard.

7. Finally add the right IP address and port to be able to access your Minecraft server

In some cases, you need to manually set a port for your connection for it to work. 

For example, if your IP address was 10.0.0.2, but you wanted to have players connect on port 25565 the default port for vanilla Minecraft, you’d need to set that as your port.
