A little while back I decided to migrate my Mojang account, but whenever I try to join an online server I get greeted with an error message that says 'Failed to login: Null' even though I know I have logged in to Microsoft with my new migrated account. This happens on the Mojang launcher, FTB and Curseforge launchers and things like lunar client, even when it shows that I have logged in. Thank you, and I hope there is a way to fix this.
