Why did I fail to connect to a Minecraft server?

You failed to connect to a Minecraft server because you might have started two instances of Minecraft and the old session ID is invalidated.

It can also happen because you’re using a cracked version of the game like TLauncher.

This is because most Minecraft servers do not allow cracked players to join them.

If you’re the server owner and you’ve set “online-mode” to “true” in your server’s properties, it can also cause connection issues,

Otherwise, there’s a technical issue on Mojang’s/Microsoft’s end that needs to be fixed.

In May, the “Failed to connect to the server” error is a known bug in the Mojang Studios Official Issue Tracker website.

The bug is categorized as a “Networking” issue here: https://bugs.mojang.com/browse/MC-262264.

If there’s an official bug in the tracker, it means that the Mojang team is investigating the issue and working on a fix.
