Skins and multiplayer not available

Since 1.17.1 dropped, the launcher opens in my account with the xbox account name, with no minecraft, and i have to change to the normal account. In that account, my account, the skins became unavailable always saying "Sorry! We could not load your skins.". The multiplayer also stopped working. Whenever i go to a server, private or not, it says "Failed to login: null", and i can´t enter it.
