### Website URL [https://clickmart45.kesug.com/](https://clickmart45.kesug.com/) ### Error Message WordPress loopback connection fails – WooCommerce background processing cannot connect ### Other Information Hello, I am using InfinityFree free hosting with WordPress and WooCommerce. My website is: [https://clickmart45.kesug.com/](https://clickmart45.kesug.com/) WooCommerce’s Background Processing Test fails with: “Could not connect. Please ask your hosting company to ensure your server has loopback connections enabled.” I am using the Meta for WooCommerce plugin, and product synchronization to Meta Commerce Manager is not working. Meta/WooCommerce connection itself appears to work, and Meta API requests return HTTP 200, but the WooCommerce catalog synchronization does not upload any products. Could you please check whether server-to-self HTTP/HTTPS loopback requests are supported for my hosting account/domain? In particular, could you check whether requests from: [https://clickmart45.kesug.com/](https://clickmart45.kesug.com/) back to itself, including WordPress background requests such as wp-cron.php and admin-ajax.php, are being blocked by the hosting environment, firewall, security system, or other restrictions? Thank you. ---

Your site should be able to collect to itself. And it can connect out to woo commerce servers. What it can’t do is let woo commerce checks connect to your site because the security system blocks bots ect ---

What you’re describing is somewhat covered by these articles: > [@Why isn't API access working on my website?](https://forum.infinityfree.com/t/why-isnt-api-access-working-on-my-website/115198): > > If you’re trying to use APIs on your InfinityFree website and they’re not working, this is due to our browser security system that’s required on all free hosting accounts. What’s happening? InfinityFree uses a security system that requires JavaScript and cookies to access websites. APIs and automated tools typically can’t execute JavaScript or store cookies, so they get blocked by the security system. When API clients try to connect, they usually receive a “403 Forbidden” error or a HTML respo… > [@WordPress Site Health warnings on free hosting](https://forum.infinityfree.com/t/wordpress-site-health-warnings-on-free-hosting/78910): > > WordPress includes a Site Health tool that checks your website’s configuration and reports potential issues. You can find it under Tools → Site Health in your WordPress admin area, or it may appear through plugins like Health Check & Troubleshooting. Don’t worry if you see multiple warnings when running these checks on InfinityFree. Most warnings are completely normal and expected on free hosting.

While this protects your site from malicious traffic, it can affect certain types of access. How the security system works The system checks that visitors can execute JavaScript and accept cookies: features that all modern web browsers support. This verification happens automatically and most website visitors will never notice it. You may occa… In short: any connections to your website that’s not from a browser will not work. This includes WordPress’ own loopback connections, as well as any API calls or webhooks _to_ your website (API access from your website to other providers, like Meta, do work). WordPress cron jobs can be run using regular WP Cron, which runs some background tasks alongside regular web requests, If you need to help the cron along for some reason, you can just trigger it directly by opening the URL `https://clickmart45.kesug.com/wp-cron.php` in your browser. For most websites, this is not a big issue, and WordPress cron updates getting stuck is usually caused by bad jobs blocking the queue, not by lacking cron job or loopback request support. But this applies mainly to vanilla WordPress. WooCommerce is a much more complicated beast, and so are the wealth of plugins on top of it to integrate with external marketplaces, which may have their own dependencies and complications. All in all, I’m 70% sure that the error you’re seeing is a red herring and doesn’t actually impact your website. But I’m no WooCommerce expert so I’m not completely sure. ---
