I try to open the open in several times and ways it never worked. Its there any special requirement?

Sorry, is forgot to update the curseforge page. To create the portal you need a 5x5 frame of stonebricks and in the middle 3x3 flowers. And then sneek right click with bone meal.

Or do you mean loading the mod? If then you need u-team-core to be installed: https://minecraft.curseforge.com/projects/u-team-core
