When i try to log onto servers like 2b2t, Hypixel or Wynncraft the loading screen will just say: "failed to log in: null". What do i do? I have a suspicion that it has something to do with the fact that i have migrated my account to microsoft, since the problem wasnt occuring for me earlier. However it is possible for me to start a completely normal singleplayer world. I use Optifine or Forge but even if i try in vanilla the problem will still occur. What do i do?
