We use the Jetpack connection to provide remote services including benchmarking

Yes, this plug-in requires a working XMLRPC.php and a WordPress.com account. These are both required in order to securely connect to our cloud services (eg our benchmarking API) which help power the plugin.

By using the same account and communications layer as jetpack we benefit from the incredible maturity and performance of that system, and we also help our users by not requiring them to sign up for a whole new service if they already have a WordPress.com account.

If you already have jetpack installed we allow you to automatically reuse that connection without needing to sign in again. Other plugins that do this include WooCommerce and WCPay.

Thanks for trying boost! Can I ask the URL of the website that you are trying to connect? That will help us analyze the possible sources of this error.

This error usually occurs when there is an issue with your XMLRPC.php endpoint and/or a conflict with another plugin on your site.

We are actively looking into this bug. Can you let me know the URL of the site, and/or which theme and WP version you are using?

Thanks,
Dan
