Multiplayer, Clients can't join

[mazaraz 10]

Recently I started a Multiplayer server with the intent of having a friend join me (he bought and downloaded the game explicitly to play with me). But every single time he joins, he connects is stuck spectating and then it shows he disconnected, we tried removing all addons, we tried having him host and it was the same thing only from my end, we tried different maps, different settings, different circumstances (i would save the game/not save, be in lobby, be in game) nothing seams to work, some assistence would be appreciated.

Hi mazaraz, do you have TKOM blocked by a firewall by any chance? This sounds like a firewall issue. Make sure both of you do not have it firewall-blocked.
