Is the headless linux broken ?

Hi,

I am deploying my game on a EC2 server, on wich i run a linux headless version as the host.
When the game starts a lot of buildings dont have their colliders at the right place ?!

The strange thing is: when i run server and client on (Pc standalone - editor) or (Pc standalone - Pc standalone) everything works fine.

The buildings have network identities on.

I looked at everything, i dont have a clue what it could be ...

[EDIT]
I got two warnings that i dont have using standalone or...
