Ark: Survival Evolved - shutting down game on dedicated server

Hello, I have a problem with the Ark: Survival Evolved game on the dedicated Windows 10 Store PC server version (Ultimate Xbox membership). I played a game on the xbox, as two buddies, two more on a Windows 10 PC. I switched to PC too, synchronization
went well, I started playing, but after 1-30 minutes the game exit on the dedicated server, without fail, it just closes and the game doesn't save. It only happens when I play on the PC, if I try to play on the xbox console it goes fine. I tried deleting my
profile from the dedicated server in AppData and starting over, but the dedicated server keeps falling. I even tried to create a new Xbox account. I turned off the sync on the xbox. I also made Windows 10 Home factory settings, clean game installation, and
updated drivers, both on the client and server. It occurred to me that this was some kind of network problem, since I was the only one playing from the same network as the dedicated server (but the functional xbox also :-/), the others are connecting over
the Internet. Nothing usefull in event log. Any ideas? Thanks so much in advance.
