Can’t join my server

So I was going on to my server today and when I did try to join it gave me this error:

internalexception: io.netty.handler.codec.decoderexception:java.lang.indexoutofboundsexception: index: 25. size: 5

server version: forge 1.16.5

username: BlueRoseAce

launcher: minecraft official launcher

server: cracked

please help

It doesn’t not, when I go back to a back up from before this problem and the mods I added it lets me in so maybe it could be caused by a broken mod

the mods currently on the server before the problem are:

journeymap

twilightforest

tinkers construct

aiotbotania

angrlring

apothosis

appleskin

botania

clumps

common capabilities

curios forge

cyclops core

evilcraft

heyla forge

integrated dynamics

jei

jer

LibX

Mantle

morpheus

mythicbotany

neat

patchouli

placebo

servertabinfo

useful backpacks

u team core

fastleaf decay

and the mode added right before which can be broken or i’m compatible are:

cofhcore

disenchantment edit table

inventory sorter

scaling health

silent lib

thermal expansion

thermal foundation

some of the dependencies may not be in the right category because I can’t remember which mods some are for

I got it to work, the problem mod was scaling health so I got rid of it and it worked, I think the mod needs to be installed on world gen to work or else it breaks with the wrong world type for the mod

how do I close thread ;-;
