Minecraft error 503 means that the Mojang servers are down. When the session servers are down, you may be able to log into Minecraft itself, but you’ll be unable to join any server with online mode enabled as that server will need to authenticate the user’s Minecraft name and will be unable to. This is when ‘An error occurred (503) will be displayed in Minecraft.
This error could be caused by a lack of internet connection, or just failure to connect to Mojang servers. If Minecraft cannot confirm your registered copy of the game, it will not allow you to join a public server. This is done to prevent piracy.
Sometimes, your internet might not be down, but Minecraft just might have trouble connecting to Mojang servers. If this occurs, exiting the game and restarting the game will work most of the time.
Another instance where this error could occur is if you’re playing on a ‘cracked’ account attempting to connect to an online server. Since cracked accounts are exclusively separate from Mojang authentication servers, they cannot connect to online servers such as Hypixel or 2B2T.
Firstly, make sure you’re running a stable internet connection. Error 503 is usually caused by not being connected to the internet, so this will be the most obvious step.
Next, close and restart your game and possibly your computer. You could just exit and reconnect to the server, but to be safe restarting your game will give Minecraft another opportunity to reconnect to Mojang servers.
Lastly, just make sure you’re playing on an authorized version of the game. If you’re playing on a cracked account, you cannot play on online servers.
To conclude, Error 503 is a pretty simple issue that’s fairly easy to fix. Mojang has to authenticate every account to prevent piracy as best they can which is the origin of this error. I hope this guide was able to help you get past the error and learn how to fix it in the future. With that said, have a great day!
