Fix C9 Error

Hello
My server have 2 IP: Local IP and Public IP

I config my server with Local IP and use my Public IP to run client. But when I connect to game I got C9 Error.

Any one know how to fix it?

Thanks anyway :)

If you are going to be hosting a public server and don't know how to fix it something as simple as this, im afraid you shouldn't be trying to host a server.

you make my day realy this is a joke or what? all ppl who make a server know if you use a local ip on server you have to use same IP on client to can connect is logic so you have to use a public ip on server and client i hope this was a joke...

^^ Oh I knew how to run a server but I just wonder how to run a server if I have a server have 2 IP like I said

only if have 2 ip public
