error in login failed: authentication is currently disabled for maintenance

I had pirated Minecraft a while ago, but then I decided to buy it a few days ago with the 50% discount to play premium servers. When I go to the servers I get that I can't join because error in login failed: authentication is currently disabled for maintenance, I already did I followed everything step by step when several people here got that error, for example MC-207896, and I still cleaned my DNS, I checked my internet connection, I restarted my PC, I deleted all the Minecraft folders there are and still I get that error, I already verified that there are no traces of pirate Minecraft and I still get that error
