Fix: ERR_CONNECTION_RESET on post save or add media in wordpress

The “ERR_CONNECTION_RESET” error typically occurs when the connection between your web browser and the server is interrupted or reset. This error can be triggered by various factors, including network issues, server misconfigurations, or conflicts with plugins or themes in your WordPress installation.

Here are some steps you can take to troubleshoot and resolve the “ERR_CONNECTION_RESET” issue when saving posts or adding media in WordPress:

1. Clear your browser cache: Start by clearing your browser cache and cookies. Sometimes, outdated or corrupted cache files can cause connection issues. Close your browser completely, reopen it, and try accessing your WordPress site again.
2. Check your internet connection: Ensure that your internet connection is stable and working properly. Try accessing other websites to confirm that the issue is specific to your WordPress site and not a general connectivity problem.
3. Disable VPN or proxy: If you’re using a VPN or proxy service, temporarily disable it and see if the issue persists. Sometimes, these services can interfere with the connection to your WordPress site.
4. Test with a different browser: Switch to a different web browser and check if you encounter the same error. If the issue is browser-specific, it could be related to browser extensions or settings. Try disabling any extensions or using a clean browser without any modifications.
5. Disable plugins and switch to a default theme: Temporarily deactivate all plugins on your WordPress site and switch to a default theme like Twenty Twenty-One. This will help identify if the error is caused by a plugin or theme conflict. If the issue disappears, gradually reactivate your plugins one by one until you find the culprit.
6. Increase PHP memory limit: Insufficient PHP memory can sometimes lead to connection issues. Increase the PHP memory limit in your WordPress installation by adding the following line to your wp-config.php file:

define('WP_MEMORY_LIMIT', '256M');

This will set the memory limit to 256 megabytes, but you can adjust the value as needed.

7. Check server logs: Review the server logs for any error messages related to the connection reset. Contact your web hosting provider for assistance in accessing and analyzing the server logs.
8. Contact your hosting provider: If the issue persists and you have exhausted all the troubleshooting steps, reach out to your web hosting provider for further assistance. They may be able to identify any server-side configurations or network issues causing the connection reset error.

By following these steps, you should be able to diagnose and resolve the “ERR_CONNECTION_RESET” error when saving posts or adding media in WordPress.
