I've checked that, it should be able to pull down another at least one millimeter more before bottoming out.

What do you mean by not correctly aligned? I tought it can only be assembled in one way, because of the notchings.

Depending on the hub…you may or may not need a spacer if the rivet/bolt is flush/flat. If I don’t insert the spacer, the lock ring bottoms out and doesn’t completely tighten the cassette onto the hub. I was able to purchase spacers of varying thickness at an LBS. If this is in fact your issue…remember that the spacer can go either before the cassette, or before the lock ring. And, it will likely require the shifting to be adjusted. — Dan
The lock ring is not bottoming, it's pushing the casette down. If I put a 2mm spacer behind the casette, I might not be able to tighten the lock ring, because it cant reach the thread in the hub. Is it safe to use a narrower spacer behind the casette? I might be able to fit in 1mm.

A FH-TX505-8 is a 8 speed free hub that is compatible with 9 speed cassettes, but I'm not sure if that moves on up the road in compatibility with 11 speed cassettes.
It's listed to be compatible with 11 speed, picture is from shimano's website.
Also to answer some:
There is no wear on my hub, it's almost brand new. I've checked the threading on the lock ring and in the hub before, it appears to be fine.
Thank you for all your answers. I've made a video of the problem.
Please note that i'm pushing down on the pedal so the hub is tightened.
At the moment the casette is also tightened way above the recommended torque range, between 50-60 nm.
At 40 nm the movement is about the same, but it requires less force to jiggle.
