My friend can't connect to my server

[Navaro]

When my friend joins his console says

Connection established
Killing other pending connections
No matches

And his loading bar says "Connection Accepted"

We can't figure out what is causing this problem.

He also says that he cant see the welcome message and he doesn't see that he has become Super Admin.

It's just him apparently my other friends can join fine.

It's probably his problem if your other friends can join just fine.

I try to tell him this but he denies and says it's me because he can join other servers fine.

I'm sorry then, I can't really help you.  I have no clue what could be happening.

No, he lives over 3 hours away from me. We're not on a LAN nor use the same ISP.
