I found a Minecraft 1.20.1 Forge modded server that runs with a mod setup you grab through CurseForge.
They have a Discord where you can get the mods and also find the server info so you can join once you are set up.
If you want modded Minecraft and do not mind importing a pack this one is made for that.

I found a server where the owner is trying to get a small group together. They want around five people to join and play.
To get in you need the Crackers Wither Storm mod and TACZ. It sounds like the whole point is to play together with those mods and just have people to team up with.GG.MINEWIND.NET New Server IP
