API Error: Invalid server response.

  • Hello Support Team,

    I just tried to start the SEO Analysis.
    I runs to 100%, then it waits a short time.
    Then I get the “API Error: Invalid server response”
    See screenshot:

    I found a similar ticket, but there was no solution it seems.

    I would be happy about any help.

    Best Regards

  • Hello Sitesupport,

    The HTTP 1.1 request doesn’t make a difference, the result is the same.

    When testing with the URL getprint.co.il it works correctly, no issues there.

    The URL https://rankmath.siterubix.com/wp-includes/css/dist/block-library/style.min.css?ver=5.3.2 works fine as well. This means the issue is probably related to the SiteSpeed caching?

    I also tried with the URL https://rankmath.siterubix.com/hello-world/ and it failed with a timeout error just like the homepage. It also fails (with a timeout error and a 404 response code) on non-existing URLs like https://rankmath.siterubix.com/hello-world/x

    If you change anything in your setup and then want to test, you can use our online analyzer: https://rankmath.com/tools/seo-analyzer/

    Please let us know if there’s anything else we could do to help you troubleshoot this issue.

    Thank you. Looking forward to your response.
