@MojangSupport Good Night and sorry to bother, but since Wednesday I were having a problem with my Minecraft account. That day I migrated my account to a Microsoft one, and I can open the launcher and load the game, but when I try to enter a server, a message displays saying -

"Failed to login: null" and I literally tried everything, I reinstalled the game, I uninstalled it, I loggued out and in, I tried putting an family account to see if it was child control, but literally nothing worked. btw, my account is Lolocrafter246
