friend connection error

[hellomynameisaj]

hi i tried to let my friend join my server and whenever he logs in he gets the "you've been disconnected" error. i've tried giving him other accounts and checking his realm list but nothing fixes it and he's turned off his firewall.
all my other friends can join so i am 98% sure its on his end any suggestions on how we can fix it?
i'm on the the free version 7 of 4.3.4 repack. i am really hoping he can get on.

If all your friends are able to log into your server and only one of them is having problems, that is certainly the problem. You need to check his client version and also if there are any errors in the client files. Can it get on servers other than yours?

is client is fine he is using the same as my friends are using. i think its something with his internet, i've tried a server with hamachi to and it just says he has a relayed tunnel and he can't get on.

Check router and firewall settings.
