- Restart and try again: Network errors can be intermittent, and you may simply need to restart Minecraft and wait for background processes to complete.
- Check your internet connection: See Troubleshoot Minecraft Network Connection Errors for suggestions.
- Sign out and sign back in: See Reset Your Microsoft Account Sign-In in Minecraft for information about resetting your Microsoft account sign-in on your gaming system.
