So I usually run a server every so often, but I didn't for a week or two. Someone wants me to host a map for them. I started the server and after a few seconds it goes "disconnected from master server."

Now I know how to port forward, I already have my firewall accepting it. I want to know why It doesn't work now. And how can I fix it.

have you the latest version?

Yes. But I'll redownload the game and try again.

Edit;

Still doesn't work.

Check your current IPv4. Compare the IPv4 digits with the ones you have set into your port forwarding Server IP. If the Server IP does not match your current IPv4, change it so it does.

After changing the address, it may take a few minutes to go into effect.

AWWW YEAH!

I didn't have a security code, and people were stealing my internet. Just secured my network.

But thanks Sound. My IP changed or something, hopefully I can get a server up.
