It's been awhile since I chased down my nether portal's location and I made two abortive attempts before figuring out the correct location.... which happens to be right smack dab in the middle of a path... no kidding.
However, the orientation of the portals don't match... so maybe the one in the nether could be rotated? I'm tired so have to get out of there tonight. Anyway, mine is very close to spawn... it' unlabeled and you have to run through it to continue down the hallway...
Sorry
