You have invalid player skulls somewhere. Mojang recently change something in their API which manages skins, player names, UUIDs and such. And previously valid skulls which make requests (to get the player skin) aren't anymore.

First all, you have a excesive amount of plugins on your server... incluiding some same plugins with diferent versions. You should free your server a little bit.

About the all IllegalArgumentException: Obiously the API changed and the previous heads are nonexistent. The next reply is the correct answer:

The correct way to fix it would be try and catch the problematic heads and remove them.

Alright, I'll try to find the heads and remove them, thanks for the help

Have you been able to find these heads? And how so?

 

[DuneSciFye]

I haven't found them yet, I have no clue where to start. I'm going to try and change out the hub to a new one and see if that fixes it today

I updated the hub and its still giving me these errors. The only worlds I have are Skyblock, Skyblock_nether, Skyblock_the_end, Superiorworld, Superiorworld_nether, and Superiorworld_the_end with Skyblock being the hub and Superiorworld being the world the islands are stored on. I basically renamed the current region folder in Skyblock to regionold and uploaded the new region folder with the new hub. I also deleted Skyblock_nether and Skyblock_the__end. Could it be something in the Superiorworld world?

Run the server with -DPaper.debugInvalidSkullProfiles=true, it should produce more info to see where that invalid data is coming from

I added the java flag, and restarted my server. Here's the error: https://pastebin.com/gfyXqMZs
I also switched to purpur a few days ago, I can switch back to paper if y'all want me to test it on paper
