Server not starting or crashing:

• Insufficient resources: Make sure your server has enough RAM and CPU resources allocated. If the server consistently reaches its resource limits, consider upgrading your hosting plan or optimizing server settings.
• Incorrect Java version: Ensure you have the correct Java version installed on your system, as Minecraft servers require specific Java versions to run smoothly. Check the server software documentation for the recommended Java version.
• Incompatible or outdated plugins/mods: Check for updates or compatibility issues with your plugins or mods. Remove any plugins or mods causing conflicts or crashes.
• Corrupted world files: Restore a backup of your world files or start a new world if necessary. Regularly backing up your world files can help prevent data loss due to corruption.
  
  

High latency or lag:

• Overloaded server: Monitor your server's resource usage to identify potential bottlenecks. Optimize settings, plugins, and mods to reduce the load on the server. Enabling view distance reduction and disabling resource-intensive features can help alleviate lag.
• Network issues: Check your server's connection to the internet and contact your hosting provider if necessary. Ensure the hosting provider offers stable network connections and low latency.
• Geographical distance: Ensure your server's location is geographically close to the majority of your players to reduce latency. Consider using a Content Delivery Network (CDN) or proxy service to improve connection quality for distant players.
  
  

Connection issues for players:

• Whitelist or ban list: Verify that the player is not banned and that the whitelist is properly configured. Ensure the player's username is spelled correctly when adding them to the whitelist.
• Server address: Make sure the player is using the correct server address and port. If using a domain name, ensure the DNS records are pointing to the correct IP address.
• Server status: Ensure the server is online and accepting new connections. Check the server console for error messages or warnings related to connection issues.
  
  

Plugin or mod-related issues:

• Installation errors: Verify that plugins or mods are installed correctly, and that any required dependencies are also installed. Ensure the plugins or mods are placed in the correct directories within the server files.
• Configuration errors: Check the plugin or mod configuration files for any errors or inconsistencies. Read the plugin or mod documentation for information on properly configuring settings.
• Compatibility issues: Ensure your plugins or mods are compatible with your server software and version. Keep in mind that some plugins may not work with specific server types or Minecraft versions.
  
  

Permission issues:

• Incorrect permission settings: Verify that the player's permission group is correctly configured, with the appropriate permissions assigned. Consult plugin documentation for information on configuring permission nodes.
• Plugin or mod conflicts: Some plugins or mods may override default permission settings. Check for conflicts and adjust settings accordingly. In some cases, you may need to use a permission management plugin to control permission settings more effectively.
  
  

Difficulty updating server software:

• Backup your server: Before updating, create a backup of your server files, including world data, plugins, and configuration files. This ensures you can revert to the previous version if any issues arise.
• Check for compatibility: Ensure your plugins and mods are compatible with the new server software version. Update or replace any incompatible plugins or mods.
• Follow update instructions: Follow the server software update instructions provided by the developers or your hosting provider's documentation. Some server types may require manual updates, while others may offer automatic update options.
