Trying to play multi but kicks us

[SerSmokeShop]

A friend and I are trying to multi and every time one of us tries to join the lobby it kicks us out. We've got all the same mods. all mods up to date. we both own the dlc. Can anyone offer assistance?

There are NO BG3 DLC out.

Mods will kill your game, regardless of single-player or multi-player.

Was there no message about why the connection was rejected?

If it's Error 66, you and your friend must both own the game on Steam, then invite your friend through Steam to make use of Steam Datagram Relay.

Steam-to-GOG won't work this way, since both of you appear to either be behind CGNAT, Dual Stack Lite or block the use of UPnP for automatic port forwarding.

The game uses peer to peer.

I like your tech speak.

I'm trying to follow along to fix my Multiplayer game.

I'm not super tech savvy, so what you said... I have no clue what it means. Could you, please, break it down for a simpleton like me?

There is a DLC. you get a hat, a cape and some other stuff from the D&D movie.

And yes there was a message and I took a pic of it but cant post it here I guess

"Connection failed: server has different mod version - Server (GustavDev:4.2.100.3698389),Client(GustavDev4.5.500.4403056)."

at this point we are trying with no mods and it still wont let us

Because there are more humans than IPv4 addresses, ISPs assigned one such address to multiple customers. This technique is called Carrier Grade NAT. If you get IPv6 as well, it's Dual Stack Lite.

ISPs that use this technique will cancel all incoming connection attempts because they don't know to whom this connection was meant as there are multiple customers that could be behind the IPv4 address.

Steam has a transparent service called Steam Datagram Relay. It works like a VPN between players and gets around these issues, but only works for games owned on Steam and only if the connection is between Steam users.

is the other player on Mac? Hotfix 16 is not available for players on Mac yet. If not, make sure you are both updated to the most recent version.

Ok. This is a common problem. It means your Mulit-Player sync file is now mismatched. The solution is for both of you to delete this file:
modsettings.lsx

It is located in:
C:\Users\USERNAME\AppData\Local\Larian Studios\Baldur's Gate 3\PlayerProfiles\Public

You can access the AppData\Local directory by putting this string into the Explorer address bar:
%localappdata%

It will be recreated and in sync when you both start BG3 again.

Good Luck

Thank you!


We are inviting each other through Steam and from the game itself.

Both options still do not work. We connect to the local bby for a moment and then get booted.
