I have a problem here and it really upsets me after trying to deal with it for the last three hours.
So I wanted to build a big Nether hub in my survival world. I created
the first portal some time ago, now I have the materials needed.
The portal's postitions, as well as in overworld as in the nether,
are not quite good, so I wanted to change the portal in the Nether
first. According to the wiki, in a radius of 128 blocks the new portal
should connect to the old portal. Nope.
So after clearing out a platform the new portal spawned me right in
the middle of nowhere. I destroyed the portal, went back to the Nether
through the old overworld portal and built a new portal closer to the
position of the original portal. But the same thing happened again,
although the portal's almost on the same coordinates as the original,
game-made portal, the game crated a whole new portal a few hundred
What am I doing wrong? Seems like I don't understand the mechanics of the portals >.<
I think the coordinates of all portals are helpful:
Original Overworld Portal: -117 / 63 / 132Newly built Nether Portal, almost at the position of the original Nether Portal: -18 / 50 / 35Newly generated overworld portal: -164 / 63 / 275

There's a block? Break it. There's a creeper? Slay it. There's a diamond? Get it!
A portal in the Nether has to be within 16 blocks horizontally of its calculated position to hook up to the right Overworld portal.
A portal in the Overworld can be 128 blocks horizontally away from its calculated position to hook up to the proper Nether portal both ways.
Going from the Overworld to the Nether the OW portal can be 1024 blocks from its calculated position (if there are no other Nether portals closer) but you won't be able to go back from the same Nether portal.
The 128 block offset is at the end you're traveling to, since you divide/multiply the X and Z coordinates by 8 the 128 blocks in the Overworld convert to 16 blocks in the Nether.
