Server suddenly unjoinable.

[CheifyX]

Me and my friend were going to play at my server but it doesn't work.
My ping is ---.

He is stuck at Sending punch packet. I think this is related to my dad unplugging the router and plugging it back in again but I'm not certain.

Firewall is checked for Blockland, both home and public.

HELP!

You have no idea what you're talking about.

Is it only your friend that's unable to join? Or is no one able to join? If so,

Try Port Forwarding

Unplugging your router shouldn't affect it, but try logging on it anyways to see if all the settings are fine.

This usually means that you need to try port forwarding. If it doesn't work, you did something wrong. If not, you need to give more information about the issue. Is it a LAN server or Internet? Are you attempting this with a dedicated server? Can anybody other than your friend connect? If you don't know how to forward your ports, look at this tutorial: http://blockland.us/portforward/index.html
