The server crashes when I enter the nether.

Well my problem is that when generating a new world everything seems correct, but when I enter the nether through the portal, my character (his hand) appears with everything in black and then the server closes and crashes, I have many mods and I already tried remove and put a lot but I can't find the solution, I hope you can help me.

maybe try generating a new world?

I have already generated 3 different worlds

I'm assuming its a error with a chunk in the nether or something that's corrupting the chunk since it said "Exception generating new chunk"

There's a solution for that?

I already solved the problem, it turns out that one of the Biomes O' Plenty biomes caused some incompatibility and the chunks crashed.
