Minecraft generates a new nether portal in a different location that's not my home portal

Minecraft generates a new nether portal in a different location that's not my home portal - Modern villa with spacious yard in winter

So here's what's going on.

I'm going to be calling my portal at home HP (Home portal) for short, and the portal that takes me back to the overworld NP (Nether portal)

Today I was testing out the HP I just built to see what part of the nether it would take me to, and it all checks out pretty good. When I stepped through the NP to take me back to the overworld it took me to the other side of the island I was building on instead of taking me back to HP. (I will call this other portal OP) I destroyed the OP and went back home to enter the HP again to see if it would happen again. Going through the NP back to the overworld, I was spawned in the exact same spot the OP was located in and it spawned the OP again. So truly I have two questions;

  • why is this happening?
  • how can I make the NP take me back to the HP instead of the OP?

Additional information that may or may not be of use:

  • I play bedrock on a PS5
  • no additional portals were ever build in the nether, only the one NP
  • HP is located in a room I made inside a mountain, a fair distance above what I'd call "ground level"


Best Answer

This frequently happens to a lot of people. Think of it like this:

You build a nether portal, you enter it

Nether portal spawns in nearest cave/opening

However, when the coordinates are calculated from nether portal back to overworld, it cannot find your orginal portal, and therefore makes a new one where the portal is supposed to be (based on portal nether coordinates).

Try building your overworld portal closer to where the nether portal kept spawning in. It should link up.

This answer does not contain how nether portals really work so as to keep it simple.

Why does my nether portal keep spawn me somewhere else?

Note that the game will only scan within the map height. That means that if you place a portal above the nether ceiling, it won't be found, and the game will create a new one for you. However, sometimes the game will put the Nether portal far from the starting point, if it can't find other suitable place.

Why did a second nether portal appear?

This is most likely a rounding bug where the spawned portal in the nether, when trying to find a portal back in the over world, does the search but due to rounding and the 8 to 1 conversion rate, it will not find your original portal.

Can you make your nether portal spawn somewhere else?

Because the portal might have been adjusted, you need to go even further away, say 1100 blocks. This will spawn you somewhere else in the Nether.
