hopefully you're not super unlucky (Like i was) and your world doesn't have a portal, which has happened to me on multiple occasions. Good luck finding it!

Thanks guys, i did used the eye of ender and i got to the coordinates and dug down, found the stronghold, but i only found a huge liberary but not the portal, ive explored many hours but cant find it :(

If the eye of ender stops at 30 does this means the portal is on 30 also?

Thanks all :)

You can use Eyes of Ender to find the portal, or use the command "/locate stronghold" (i think its stronghold). Then it should tell you the coordinates and you can click on them to teleport to it, if you tp above ground then all you have to do is dig down.

Bruh just use Eye of Enders
