Worlds don't work on server

hi everyone! have such a problem: I created a server, everything works, but: all portals from mods lead to an empty dimension, the player’s texture is not displayed and you can’t move. the only way out is to write kill. The portal to hell is not working - the screen becomes cloudy but nothing happens. when you enter the ender portal, it doesn’t take you anywhere, but immediately gives you the Perfect Escape achievement. couse, in single-player, everything works

Mind tell us the mod that creates the portals? And provide a list of mods and minecraft version?

1.12.2, mods on extra dementions:YAMDA, Aroma1997.
All mods:

and i fixed nether, it whas turnd off in server-settigth…

Has that also fixed the no moving issue and player texture issue?
