    We have an issue with our WooCommerce Webshop. When a customer finishes their order, the website loads for 60 seconds. Then a red banner with “Gateway Timeout” is shown. But the email for the order is sent (after the 60 seconds).

    In the console, I see this log entry: Failed to load resource: the server responded with a status of 504 (Gateway Time-out). The loaded resource is /?wc-ajax=checkout

    I tried to deactivate the mail SMTP plugin. Then the result page showed up correctly, but the mails have not been sent anymore. I tried to use a different SMTP plugins, but that did not help either.

    This is the complete system status:

    Hi @ckarisch

    Based on the information you’ve provided, it seems that the issue is related to the SMTP plugin that you’re using, as deactivating it resolved the Gateway Timeout problem but caused the emails not to be sent. Here are a few steps to help you troubleshoot and resolve this issue:

    1. Update all plugins, themes, and WordPress core: Ensure that you’re using the latest versions of all your plugins, themes, and WordPress itself. This is important because updates often include performance improvements and bug fixes, which may resolve the issue you’re experiencing.
    2. Check for plugin conflicts: Temporarily deactivate all other plugins except for WooCommerce and the SMTP plugin. This will help you determine if there’s a conflict between your plugins that’s causing the issue. If the problem persists, try using a default Storefront to rule out any theme-related issues.
    3. Verify your SMTP settings: Double-check your SMTP settings to ensure that they’re correct. Incorrect settings can cause issues with sending emails and may result in the Gateway Timeout error you’re experiencing. You can find the correct SMTP settings in your email provider’s documentation.
    4. Test with a different SMTP plugin: You mentioned that you tried using different SMTP plugins, but the issue persisted. It’s still worth trying some other well-rated SMTP plugins to see if the problem can be resolved. Some popular options include WP Mail SMTP by WPForms and Post SMTP Mailer/Email Log.
    5. Enable debugging: If the issue persists, enable WordPress debugging by adding the following lines to your wp-config.php file:
    define( 'WP_DEBUG', true );
    define( 'WP_DEBUG_LOG', true );
    define( 'WP_DEBUG_DISPLAY', false );

    This will create a debug.log file in your /wp-content/ directory. After enabling debugging, try placing an order again and check the debug.log file for any errors or warnings related to the Gateway Timeout issue.

    1. Contact your hosting provider: If you’re still experiencing the issue after trying the above steps, it’s possible that your hosting provider’s server configuration is causing the problem. Reach out to their support team and provide them with the details of the issue and any relevant information from the debug.log file.

    I hope these steps help you resolve the Gateway Timeout issue on your WooCommerce Webshop. Thanks!

    Thank you for your help. I followed the steps you provided and finally found out, that the error is caused by the SMTP server. As soon as I replaced it with a mail API service, everything worked.
