Nether portal wont teleport me to the nether...

Ok so i have this problem when ever I try to enter nether and I think end is broken too. it basically does the swirly portal animation on screen but doesn't load the nether or anything...
I have mods installed too...

What have i tried:
Allow_Nether = true it was always enabled
resetting the nether didn't help
Exported the world into singleplayer (still doesn't work)
Doesn't work for other players too.
Tried to enter with an execute command shows as unknown dimension...

Bc i'm running forge the nether is Dim-1, but I noticed a folder that is called dimensions I think it was created bc of mahui tsukai mod which i removed and i also removed some files it created like a modded dimension that was created, because of the mod. (this could be the cause i will try to check it out if i can create a nether folder or so)
I checked all over and nobody seems to have an answer.

What is the address of the server in question?

why do you need it exactly? just wondering...

As part of the Aternos Staff I'm able to lookup your server in our database and check it on my own.

If you don't want to post the server IP publicly you can also send it to me by mail: roman 'at' aternos.org

I will

First, take a backup

Then remove mod by mod and check each time you removed one if the problem persists

Afterwards you know which mod causes the problem.

Hey sorry to comeback to this thread but i tried removing the mod by mod and it seems that the issue is even persisting without mods.

Quote from Roman

Then check if it persists when you switch the software to vanilla

Yup it still persists just tested it...

Quote from Roman

I checked your account log and you never switched it to vanilla

oh i thought switch my game version to survival and try the world in singleplayer. i will try that right now.

so now i made the server vanilla tried it and it still isnt working

Idk what the problem is but this should fix it:

1. Download the world
2. Upload the level.dat file to http://irath96.github.io/webNBT/
3. Navigate to Data->WorldGenSettings->dimensions
4. Right click on dimensions, choose New->CompundTag
5. Name it "minecraft:the_nether"
6. Save the file and replace it level.dat from the downloaded world with the new one
7. Upload the world again.

This is pretty hacky, take a backup before doing anything

Thanksss it worked!!!
