Had to take apart the the upper part, and dip the tip in hot water for several minutes, after that put a wrench and twisted it off slowly.
After using the Hex tool it was still stuck, which then I assumed was glue.
Worked like a charm.
I'm trying to remove my tip to give it a proper clean down from top to bottom, but it's honestly not budging.
