Server error when fetching sitemap

This error appears when the server returns an error when trying to access the sitemap. Here's what causes it and how to fix it so Google can access it without issues.

What this error means

When Google tries to access your sitemap, the server should respond with the file and a 200 status code. If instead the connection fails, Google can't retrieve the sitemap and treats it as temporarily unavailable. The problem is that if the error repeats, Google may stop requesting it regularly. That means the sitemap stops fulfilling its main function, which is to speed up the discovery and indexing of new content. Unlike an empty sitemap or one with syntax errors, here the problem isn't in the file's content but in the server not allowing access to it. The file may be perfectly valid, but if the server doesn't deliver it, Google can't read it. This error is usually caused by a server failure, firewall or WAF rules that block crawler requests, configuration issues with the CDN, or TLS certificate failures.

Why fixing the server error fetching the sitemap matters

An inaccessible sitemap is a sitemap that doesn't exist for Google. If the server can't deliver it, all the work of having it correctly configured amounts to nothing. Fixing it is a priority because it directly affects Google's ability to discover and index your content in time.

Impact on SEO rankings

Without access to the sitemap, Google depends on organic crawling to discover new or updated pages. That can delay their appearance in search results and directly affect the site's organic traffic.

Crawling and indexing obstacles

If the error persists, Google may reduce how frequently it requests the sitemap or stop requesting it altogether. That means new content takes longer to get indexed, especially on large sites or those with frequent updates.

Negative signals for site quality

A sitemap that returns server errors signals that the site's technical infrastructure has problems. For Google, it's an indicator of instability that can affect the trust it places in the site.

How to fix it step by step

If this error showed up in your audit, here are the steps to leave it behind.

Step 1

Check what type of error the server is returning

Access your sitemap URL — usually yourdomain.com/sitemap.xml — and observe what response the server returns. A 5xx error indicates a server failure. A timeout or connection error may point to a DNS, firewall, or TLS certificate problem.

Step 2

Review the server logs and security rules

Check your server or CDN logs to identify the source of the error. Check whether any firewall or WAF rules are blocking search engine crawler requests and add their user agents to the allowlist if necessary.

Step 3

Verify that the sitemap responds correctly

Once the problem is identified and fixed, access the sitemap URL again and confirm that the server returns the file with a 200 status code and Content-Type "application/xml" or "text/xml".

Step 4

Submit the sitemap to Google Search Console

With the sitemap accessible, submit it from Google Search Console so Google processes it as soon as possible and resumes crawling the content that may have gone undiscovered during the time it was inaccessible.
