Spacebuild doesnt work on my server!

First, sorry if i posted this on the wrong board.
Im trying to run a dedicated server with spacebuild 2, but the problem is when i go to space or other planet, i can noclip in space, and life support doesnt work on space and other planet’s atmosphere, like on space doesnt have air, but i won’t die, ls2 works just under water.
Anyone can help me please???
Thank you!
