When we look at the first error (503), it is mainly related to the servers and online services.

Of course, the most basic solution you can try is restarting the game. This will confirm whether it was the game's issue or something else.

Next, you can try to restart your internet services. You can restart the WiFi router and even reset the network connection settings of the device on which you play the game.

Lastly, you can log out of the game's official launcher and log back in to resolve the issue.

If none of the above work, you must wait for Mojang to fix their server issue. You can go online to check whether Mojang's servers are down at that particular moment.
