1.20.4 server error failed to get Minecraft server from Bukkit.getServer()

I'll come right out with it. I put up this private server so a friend and I could play on it. Idk anything about coding or where to even begin to look although I might have a clue where to begin which could be in a config file somewhere.

Anyway, all I did was slap a few plugins in like Esssentials, LuckPerms, Minepacks, playit.gg for a more secure IP and Vault to help out LuckPerms.

This is a full on Bukkit server. I know a few years back a friend said it wouldn't be fully supported but it's all I know and whether Spigot and Paper are probably similar, again Bukkit is all I know. The Essentials plugin is also a few years out of date but any other one didn't look quite right when I loaded into the server.

So if there's anyway someone can help this noob coder out, I'd appreciate it. Screenshots and latest log is provided.

 

My bad, will do.

Edit: So I moved the playit plugin out first and it stopped the error. Unless someone here has experience with playit and this error, thread is still opened, other than that, this is solved. TY admin.

 

same error for me. the playit plugin is not working properly, anyone know how to fix this?
