⚠️ Common Issues

Bot Can't Assign Roles

• Role Hierarchy Issue (Most Common Problem):
  • Discord uses a top-down role hierarchy system
  • The bot's role MUST be positioned ABOVE the verified role in Server Settings > Roles
  • If the bot's role is below the verified role, it cannot assign that role to users
• Check bot permissions (Manage Roles is required)
• Verify the correct role ID is in config.yml

Verification Process Failing

• If you see "Your account is already verified" in Minecraft but Discord shows errors:
  • Try using /verify force to reset your verification
  • Check server logs for specific error messages
• Ensure verification codes are being used before they expire

Nickname Sync Not Working

• Verify bot has "Manage Nicknames" permission
• Check role hierarchy - bot's role must be above user's highest role
• Server Owner Limitation: Discord does not allow bots to change the server owner's nickname
• Enable debug mode for detailed logs

Can't Find Guild/Server

• Double-check guild ID is correct (enable Developer Mode to see IDs)
• Ensure bot is in the server
• Check intents are enabled (Server Members Intent required)

2FA Not Working

• Verify Discord bot is properly configured
• Check permissions are set correctly
• Ensure player has verified their account first
