Why Your Website Submitted Sitemap Shows "Couldn't Fetch" Error message On Google Search Engine Console?
When you submit a brand new website on Google Search Console (GSC) and you see the submission successful message you expect your site discoverable and google will crawl and index your website soon. But you see a red sign of "Couldn't fetch" error message next to your sitemap even the submission was successful. It is a frustrating sight, especially when you know your site is live, your URLs are valid, and your server is responding correctly.
This status is a common point of confusion for developers and SEO experts now a days. Based on recent research into sitemap behavior, this issue occurs mostly on every new website sitemaps. Specially Astro and Cloudflare-hosted sites often gets this issue mostly. However getting this error is frequently a misleading indicator of your site's actual health.
Why Couldn't Fetch Is Often Misleading
In many cases, "Couldn't fetch" is not a permanent failure or a sign that your site is blocked. Instead, it is often a reflection of a delayed or stale processing state within Google's infrastructure.
Google Search Console does not always update its status in real-time. If your server is returning a successful HTTP 200 status code, Googlebot is likely still able to crawl your pages, index your content, and rank your site effectively. The error message in GSC is a reporting lag, not a reflection of your site's accessibility to the search engine.
Quick Verification Checklist
Before you spend hours debugging your infrastructure, verify that your sitemap is actually accessible. You can perform these checks manually to confirm that your server is behaving as expected.
First, check the HTTP status code. Your sitemap should return a 200 OK status. You can verify this using a simple curl command in your terminal:
curl -I https://yourdomain.com/sitemap-index.xml
Second, ensure the content type is correct. The server must serve the file with the application/xml content type. If it is served as text/html or another format, Google may struggle to parse it.
Third, validate the XML structure. Ensure your sitemap is well-formed and that all URLs are absolute, HTTPS-compliant, and reachable. If you are using a sitemap index, verify that the child sitemaps referenced within the index are also valid and accessible.
Finally, check if your server is blocking Googlebot. Ensure that both normal users and the Googlebot user-agent receive a 200 status code and that no challenge pages (like CAPTCHAs or interstitial redirects) are being triggered.
The Astro Sitemap Index Context
If you are using Astro, you might be using the built-in sitemap generation tool. Recent reports indicate that Google Search Console has shown intermittent issues with sitemap-index.xml submissions from Astro sites since around March 2025.
This appears to be a specific quirk in how GSC processes these index files. If your index file is valid but GSC continues to report "Couldn't fetch," try submitting the child sitemap URL directly to GSC. Often, submitting the specific child sitemap resolves the issue faster than waiting for the index file to be processed by Google's systems.
Cloudflare and Firewall Considerations
If your site is behind Cloudflare, it is natural to suspect that your firewall settings might be interfering with Googlebot. However, "Couldn't fetch" is rarely caused by standard Cloudflare configurations unless you have aggressive custom zone firewall rulesets in place.
Check your Cloudflare dashboard to ensure you do not have custom rules blocking Googlebot. If you are using Cloudflare Web Analytics, ensure the beacon script is not interfering with the XML response. In most cases, if you have no custom firewall rulesets, your Cloudflare configuration is likely not the culprit.
What to Do Next
If you have verified that your sitemap is accessible, returns a 200 status, and is correctly formatted, the best course of action is patience. Since the error is often a reporting delay, the status will frequently resolve itself without any intervention.
If you want to force a re-check, you can try the following steps:
Remove the sitemap from GSC and re-submit it.
If you are using a sitemap index, submit the individual child sitemap URLs directly.
Check your server logs to confirm that Googlebot is successfully accessing the sitemap file.
When to Actually Worry
It is important to distinguish between a reporting error and a genuine crawl issue. You should only be concerned if you see a persistent "Couldn't fetch" error with a drop in indexed pages or a lack of new content appearing in search results. Check your website has proper setup of http/https/www and has the right canonical url.
Finally If your pages are being indexed and your search performance is stable, consider the "Couldn't fetch" status as a 100% false alarm. It does not block normal crawling or ranking of your site. Focus your efforts on ensuring your content is high-quality and your site architecture is sound and fresh rather than chasing a status message that does not reflect your site's actual performance in search.
By verifying your website technical setup and understanding that GSC reporting can be delayed, you can avoid unnecessary troubleshooting and focus on what actually matters: building a great experience for your users.
