How to fix this external server error when people join my server.

[DashElector]

I've recently switched to external and have this error:

java.net.UnknownHostException: ***:25588: invalid IPv6 address literal

Is there any fix to this. My external port is 25588, which I configured in the settings. My server name is Freedex and it works connecting with the direct external server IP but not from Minehut.

Thanks to anyone who responds!

That means the IP you entered into the external config area is not a valid IP.

What exactly do you mean? My IP contains numbers and points with a :25588 port at the end? Do I need to purchase a domain to use external servers then? Dedicated IP?

Make sure you aren't putting in the port in the IP field as well. The IP field should only contain a numerical IP or a domain. The port should be in the ports section.

I removed the port from the IP field and its connecting to the server. Now in-game its showing "Failed to verify username." I added the player authentication flags and its still not working

On the external server console, it shows:

[Server] [ERROR] Username 'DashElector' tried to join with an invalid session

I've tried restarting my server, game, and computer multiple times but it doesn't help.

What server type are you using? Velocity, Waterfall, Paper? That usually happens when your startup flags aren't set correctly.

#1. I'm using paper.

#2. My external server hosting is Pebblehost, it has a Pebblehost loader which allows me to copy and past the startup flags into. That doesn't seem to work.

#3. I've contacted my server host multiple times but they said they can't do anything.

If you are using their budget plan, they do not support custom startup flags. They show an option for it but it does not use it unless you have premium+

This worked for me. Thanks for the help!
