Nothing spawning in The Nether, even from a blaze spawner. (on a server)

I'm trying to kill some Wither Skeletons to be able to spawn The Wither, and kill it. But there's one slight issue. No Wither Skeletons are spawning ever, as a matter of fact nothing is spawning. So I went into the debug menu and NOTHING is in this dimension besides myself. The entity count from the debug menu.

This is... interesting, there's the capability to spawn mobs, but nothing is spawning.

The local difficulty is: 2.25 // 0.13 so mobs should spawn, right? This is also JE, not bedrock.


If you are on a server talk to the owner, they could have disabled nether or if on a server by yourself try resetting nether or destroy the portal and make a new one. If those don't work say something.
