Socket Exception error on Minecraft server

[stocktonhyer99]

I have successfully made a Minecraft server but when some one out side my network tries to connect the get a error that says io.netty.channel.AbstractedChannel$AnnotatedSocketException: Network is unreachable: no further information:

 

I have tried all the port forwarding stuff that should work as well as changed my dns

 

Any and all ideas are helpful

Something is blocking your traffic, likely this is caused by misconfigured port-forwarding, a firewall blocking the connection, or a network setup that doesn't play nicely with port-forwarding.

 

A few questions.

• What do you your current port-forwarding settings look like?
• What does your network look like?
• What is the internal IP address for the server you are hosting this on?
• Does your ISP assign you a static IP (unlikely) or a dynamic?
• Can one of your other people ping from their computer? If it can't ping it's unlikely other connections would work.  You can test if that specific port is open as well by having your friend running the following command in PowerShell.

  • Test-NetConnection <ip_address> -p <port_number>

It is an error message for a timed out connection.

 

In other words the MC client can't find the server. Make sure that the server is running and that the port is open in your computers firewall. Use a port forward testing website to check if it is working.

 

Also, Make sure that the ip being used to access the server is not private. Private ip's are 192.168.x.x, 10.x.x.x, 172.16.x.x - 172.31.x.x, or 100.64.0.0 - 100.127.255.255 (this one is used for CGNAT. Let's hope it's not that). If the ip has letters, it is ipv6. In that case you need to make sure the mc server listens on ipv6 and that your friend has ipv6.
