To check if a proxy server or VPN is enabled, access the Settings menu in your browser and look for options related to IP addresses or proxy settings. In Chrome, look for “Open proxy settings” under the System section. For Windows users, click on LAN Settings and check the “Use proxy server for LAN” option. Mac users will find themselves in the relevant menu immediately.

To disable the proxy server or VPN, deselect the appropriate IP address or disable proxy settings options. After disabling the proxy server or VPN, try reaccessing the website. If the error disappears, you must reconfigure your IP address or proxy settings or switch to another provider.

If the error persists, continue to the next troubleshooting step.

Clearing Browser Cache and Data

Your browser cache and data can sometimes cause the ERR_CONNECTION_TIMED_OUT error, especially if the cached data is outdated or corrupted. Before clearing your cache and data, you can check if the issue lies with your cache by opening the website in incognito mode or using a different browser. If the website loads correctly in these modes, your browser data is likely causing the issue.

To clear your browser cache and data, use the keyboard shortcut CTRL + Shift + Delete to open the relevant window, select the desired time range, and then select Clear.

Some scripts may exceed the allotted memory, resulting in a delayed response to the browser and causing the ERR_CONNECTION_TIMED_OUT error. To resolve this issue, you need to increase the PHP memory limit by editing the .htaccess file with the maximum available memory to prevent your website from responding too slowly.

Access the “Site Health” tool in the WordPress dashboard to check your PHP memory limit if you’re running WordPress 5.2 or higher. Increasing the PHP memory limit allows your website to utilize more resources, which can help prevent the ERR_CONNECTION_TIMED_OUT error from occurring.

If increasing the PHP memory limit doesn’t resolve the issue, continue to the next server-side troubleshooting step.

Adjusting Maximum Execution Time

The maximum execution time of a PHP script is typically pre-configured by your hosting provider, with a default timeout setting of 30 seconds. However, some scripts may require more time to complete, resulting in the ERR_CONNECTION_TIMED_OUT error.

To address this issue, you can check and increase the maximum execution time of your PHP script. It’s recommended to set the maximum execution time between 120 and 180 seconds to ensure your website has sufficient time to respond. By adjusting the maximum execution time, you allow your website to complete resource-intensive tasks without triggering the ERR_CONNECTION_TIMED_OUT error.

If this solution doesn’t resolve the issue, continue to the next server-side troubleshooting step.

Deactivating Plugins and Themes (WordPress)

To identify the problematic plugin or theme, you can deactivate them individually and check if the error is resolved after each deactivation. If you can’t access the WordPress dashboard, you can use an FTP client like FileZilla to access the wp-content directory and rename the plugins folder.

Once you’ve identified the plugin or theme causing the error, you should first check if it’s up-to-date and, if not, update it. If updating doesn’t resolve the issue, contact the plugin or theme developers for assistance.

Consider replacing the problematic plugin or theme with an alternative solution if all else fails.
