If this Nether was first generated, there should be a fortress somewhere very nearby. Every fortress I discovered is at least up to ten chunks away from the portal. Just bring lots of cobblestone, 'cause you're probably going to have to build indestructible bridges from Ghasts.
If you have your distance rendering set to short or tiny, consider putting it on normal or far for a sec just to look around. I did this at my Portal, and while I couldn't normally see a Fortress on my usual sight distance (Short) I was easily able to spot one when I turned it up, which allowed me to make my way over to it.
to:hexalobular But it says that its usefull if you have an older save where a nether fortress was not present
yeah, but that is if a world was created without a nether fortress, then in the newer versions where nether fortresses are a thing, the seed of the old save would have a nether fortress created because that seed now has a nether fortress in it. Your world, however, doesn't have a nether fortress in the nether probably because the console versions have a limited space, where as pc has unlimited basically. You just got unlucky
