Unable to join server.

I just put together a modded smp using the Fabric modloader, with about 27 mods and a few datapacks including the 1.18 world generation datapacks that was released on the Minecraft website earlier this year. But for some reason, whenever I try to join the server, I disconnect. It always just says "Connection Lost" or something like that in gray text, but never gives any other details. If you know the cause of the problem and/or a way to fix it, please let me know.

Thanks.

Oh thanks, I will fix it to see if it works then.
