I can't find the world_nether on /worlds

Hi, i want to delete my nether world and i saw the way to do it on another thread, they say "Make sure your server is online and go to aternos.org/worlds and delete [world_nether] Then restart the server. The nether world will automatically be regenerated by Bukkit."

but i can't find the world_nether on the worlds tab of the server, help.

Spigot, 1.15.2.

ok, i did it.

i think i'm on vanilla because i can't type /mv command on my server.

is it a problem ?

ok it's in vanilla

Quote from Mc88Donalds|Julian

vanilla does not seperate the nether into a wormd called "world_nether" it saves that data in the DIM-1 Folder in your main world

yeah Roman said it to me so i already deleted the DIM-1 folder, now i can create another portal it will be another place of the nether as the last portal ?
