API Error: cURL error 28: Operation timed out after 30002 milliseconds

Hello,

Thank you for contacting Rank Math today.

Please edit the following plugin file:
/includes/modules/seo-analysis/class-seo-analyzer.php

Then, change the following line (around line number 358):
$request = wp_remote_get( $api_url, [ 'timeout' => 20 ] );

Increase the timeout value to 60:
$request = wp_remote_get( $api_url, [ 'timeout' => 60 ] );

The SEO analysis should start working as expected.

Or, you could also use the online version of the tool which is just as good:

Looking forward to helping you. Thank you.

Hello,

That is quite weird. We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WP logins in the designated Sensitive Data section.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
