Unable to properly log in to Minecraft Java Edition Launcher

Ever since I migrated my MOJANG account to Microsoft, I haven't been able to log in properly, At some point, I was able to play the demo version of the game, but it recently logged out of that, so I can no longer do so.

I try to log in using MOJANG, and it pops up with this error message.

So, I go to log in with Microsoft, and when I click the button to go to the login page, I get this error message.

I have tried several ways of logging in with my MOJANG account, as well as tried on multiple days to log in both ways. If any more specification is needed, I am happy to answer questions.
