Not spawning at my nether portal when I go into the nether

So I go into my portal and i dont get spwaned in the nether where i use to. It seems i dont get spawned the 8x (or whatever it is) closer like usual in the nether. No new portal is also created when i go through the portal. Also when i want to go back through the portal to the overworld it doesnt make a portal either. 🙂
