WordPress Update failed: Connection lost or the server is busy. Try again later.

WordPress is a powerful content management system (CMS) that allows users to create and manage websites easily. However, like any software, it can encounter occasional issues. One common problem that WordPress users may come across is the “Update failed: Connection lost or the server is busy” error message. This article will explore the possible causes of this Error and provide practical solutions to resolve it.

Understanding the “Update failed: Connection lost or the server is busy” Error:

When attempting to update WordPress core, themes, or plugins, users may encounter the frustrating error message stating, “Update failed: Connection lost or the server is busy. Try again later.” This Error typically occurs when the connection between your website and the server is interrupted or when the server is overloaded with requests, hindering the update process.

Common Causes of the Error

  1. Network Connectivity Issues:
  2. A weak or unstable internet connection can disrupt the communication between your website and the server, leading to the “Update failed” Error. Ensure that you have a stable internet connection before proceeding with any updates.
  3. Server Load and Resource Allocation:
  4. If your server is experiencing high traffic or limited resources, it may need help to handle update requests efficiently. This can result in the “server is busy” part of the error message. It’s worth checking your server’s resource allocation and considering upgrading if necessary.

Troubleshooting Steps

  1. Check Your Internet Connection:
  2. Before attempting any updates, verify that your internet connection is stable. Try accessing other websites or performing a speed test to ensure a reliable connection. If needed, contact your internet service provider for assistance.
  3. Retry the Update:
  4. Sometimes, the Error occurs due to a temporary glitch. Click the “Try again” button in the error message to retry the Update. If the issue persists, proceed to the next steps.
  5. Clear Browser Cache and Cookies:
  6. Outdated or corrupted browser cache and cookies can interfere with the update process. Clearing them can help resolve the Error. Access your browser’s settings, find the option to clear cache and cookies, and follow the instructions provided.
  7. Disable Plugins and Switch to a Default Theme:
  8. Conflicts between plugins or themes can cause the Update to fail. Turn off all plugins and switch to a default theme like Twenty-One. Then, attempt the Update again. If successful, reactivate the plugins and switch back to your preferred theme individually, testing the Update after each reactivation.
  9. Increase PHP Memory Limit:
  10. Insufficient PHP memory limit can hinder the update process. Access your website’s root directory and locate the wp-config.php file to increase it. Open it in a text editor and add the following line of code before the line that says, “That’s all, stop editing! Happy blogging!”: define(‘WP_MEMORY_LIMIT,’ ‘256M’); Save the file and retry the Update.
  11. Define a Temporary Directory for WordPress Updates: In some cases, specifying a temporary directory for WordPress updates can help resolve the “Update failed: Connection lost or the server is busy” Error. To do this, you can add the following line of code to your website’s wp-config.php file, just like the previous step: Define (‘WP_TEMP_DIR,’ ABSPATH . ‘wp-content/tmp/’). This code defines a temporary directory within your WordPress installation where the update files can be stored during the update process. You can avoid conflicts and ensure smoother updates by specifying a dedicated guide. Save the wp-config.php file after adding the code, and then retry the Update. This additional step might help overcome any server-related issues causing the Error.
  12. Update Folder Permissions to 775: To address the “Update failed: Connection lost or the server is busy” Error, consider updating the permissions of your WordPress folders to 775. This can be done using FileZilla, SSH, or by seeking assistance from your web host. Updating folder permissions ensures that the necessary files and directories have the appropriate access levels for a smooth update process. Exercise caution when modifying permissions and consult with professionals if needed.

Remember, it’s essential to exercise caution when modifying your website’s core files. Make sure to create a backup of the original wp-config.php file before making any changes so you can revert if necessary.
