504 Gateway Timeout due to update_products/process_item job

Hi there,

Thanks for the details so far. Based on how the Google Listings & Ads extension works, timeouts usually point to either environment limits or network interruptions rather than the plugin itself.

Could you please share your WooCommerce System Status Report with us (WooCommerce → Status → Get system report → Copy for support) along with the approximate number of products being synced?

Paste the System Status Report into https://pastebin.com or https://gist.github.com

This info will help us check your setup and narrow down what’s causing the timeouts.

Hi @hronak,

Thank you for getting back to us. As my colleague mentioned, the issue appears to be related to server resource limits, which can affect API connections and lead to the error you’re seeing.

After reviewing your system status report, here are my recommendations:

• Please increase your WP Memory Limit to 512 MB or even 1 GB. While WooCommerce itself requires at least 256 MB, your site is running several heavy, resource-intensive plugins, and the current 128 MB is too low.
• Increase your PHP Time Limit from the current 60 seconds to at least 300 seconds, to allow enough time for connections and processes to complete.

If you’re not sure how to adjust these settings, I recommend contacting your hosting provider for help, especially for increasing the PHP time limit.

For the memory limit, you can add the following line to your wp-config.php file:

define('WP_MEMORY_LIMIT', '512M');

Hi @hronak,

Thank you for getting back and for clarifying the situation. I completely understand how frustrating it can be to run into issues like this, and I want to reassure you that we don’t make assumptions — instead, we troubleshoot step by step to be certain of the cause.

From the error, this does look related to server resources. While that may not be the only factor, it’s the best place to start. At the moment, more than 80% of the plugins on your site are resource-intensive, and with your current memory limit set at 124 MB, the environment doesn’t meet WooCommerce’s minimum requirement of 256 MB. With those extra heavy plugins, I recommend increasing it to 512 MB or even 1 GB, and also raising the PHP time limit to 300 seconds.

Because the issue happens only occasionally, it further suggests that server usage is the likely trigger. Many plugins run background processes and checks at intervals, and when several are active at the same time, they can consume all available resources. If Google for WooCommerce happens to sync at that moment, the site may crash due to insufficient resources.

If this were a widespread problem, we’d be seeing more reports. Since you’re the only one experiencing it, it’s very likely specific to your environment and setup. Working through the troubleshooting this way will help us narrow it down properly and avoid guesswork.

Since morning (IST), all of our clients ecommerce sites using ‘Google for WooCommerce’ plugin are facing an issue

To help us better understand the issue, could you confirm whether all your clients’ websites are hosted on the same server with the same hosting provider, and whether they share resources or each has its own control panel? Also, are you using a multisite setup?

When you reply, please go to WooCommerce > Status > Logs, check the most recent fatal error log, and share it with us via Pastebin.
