Since yesterday Minecraft Launcher gives this error: 

"Oh no! Something went wrong and we couldn't connect to the Minecraft Services"

(I'm logging in with my microsoft account. restartet launcher multiple times) 

The central green play button. now says "Play Demo". Seems like it can't see that I already own the game. When I click "Buy Now" and log into the store page with my microsoft account, the store registers that I already own it, and I can download it again, but the Launcher still only says  "play demo". I've made sure Micecraft launcher is allowed through firewall and even tried shutting down the firewall. I've uninstalled minecraft (jave edition) and reinstalled with a new download, but same issue.  Yesterday I played without problems.
