"Blocked due to other 4xx issue": what it means and how to fix it

A page that returns a 4xx code can't appear in Google Search or in the AI features built on Google's index, and Google removes already indexed URLs that start returning one. This guide quotes Google's definition, separates this status from its 401, 403 and 404 siblings, covers the usual causes, and shows how to confirm, fix, validate and recrawl.

What does "Blocked due to other 4xx issue" mean?

"Blocked due to other 4xx issue" means Googlebot (Google's crawler, the bot that visits pages to read them) requested the URL and your server answered with a 4xx status code that Search Console has no more specific row for. As of October 2026, Google's help page lists it as "URL blocked due to other 4xx issue" and defines it in two sentences: "The server encountered a 4xx error not covered by any other issue type described here. Try debugging your page using the URL Inspection tool" (Page indexing report help).

The rule for every 4xx code is the same. Google's crawling documentation says "Google doesn't index URLs that return a 4xx status code, and URLs that are already indexed and return a 4xx status code are removed from the index" (How HTTP status codes affect Google's crawlers).

Search Console splits 4xx responses into several rows. This is how they differ, in Google's words:

If you see 403s rather than this status, check for restricted pages first. Wix, for example, says password-protected and member-only pages return "a 403 response (forbidden)" to Google (Wix Help Center); our Wix guide covers its settings.

Which 4xx codes land here?

Google doesn't publish a list of the codes in this row. Its HTTP status code page lists the 4xx codes it meets most often as 400, 401, 403, 404, 410, 411 and 429, and adds that "Google's crawlers treat the 429 status code as a signal that the server is overloaded, and it's considered a server error." Taking out the codes with their own rows leaves 400 and 411 from that list, plus rarer codes such as 405, 414 and 451. Google doesn't say whether a 410 is reported here or under "Not found (404)", so check the code each URL actually returns.

Is "Blocked due to other 4xx issue" a problem?

It's a problem when the listed URLs are pages you want in Google, because none of them can be indexed while the error lasts. It isn't a problem when you meant to block or remove those URLs and nothing important links to them.

Google's own filter for 404s is a sensible one here too: it recommends "fixing only 404 errors that you link to yourself or list in a sitemap" (Search Console Help). Apply the same test to this row.

Treat it as urgent when:

• Pages in your sitemap are listed. You're asking Google to crawl URLs that refuse it.
• The count jumps after a deploy or a security change, such as a new firewall rule, CDN setting or rate limit.
• Pages that were indexed are listed. Google removes indexed URLs that start returning 4xx.

If the affected pages span several client sites, check which of them Google still has free before you start changing server rules.

What causes "Blocked due to other 4xx issue"?

The cause is always a server, CDN or app returning a 4xx code to Googlebot. Which code tells you where to look.

Definitions are quoted from the HTTP standard, RFC 9110.

Malformed URLs and strict servers

Malformed URLs usually come from your own links: a template that double-encodes characters, a broken query string, or links copied with stray characters. The server rejects the request with a 400 before your page code runs. Fix the links at the source, then redirect any bad URLs that others link to.

Firewalls, bot protection and CDN rules

Security layers block Googlebot more often than people expect. Google warns that protection systems "are often configured to automatically block unusually high levels of server requests," and that "because Googlebot often makes more requests than a human user, it can trigger these protection systems" (Search Console Help). Such a rule can answer with any status code it's set to use; if that's a 4xx code other than 401, 403 or 404, the URL lands in this row.

Don't use 4xx codes to slow Google down. Google says "Don't use 401 and 403 status codes for limiting the crawl rate" and that 4xx codes other than 429 "have no effect on crawl rate." To keep Googlebot away from a section, use robots.txt; our guide to URLs blocked by robots.txt covers the trade-offs.

Geo and legal blocks

Geo blocks catch Googlebot because of where it crawls from. Google says "the default IP addresses of the Googlebot crawler appear to be based in the USA" (Locale-adaptive pages), and asks you to treat it like any visitor from the same country. A site that returns 451 to US visitors will return it to Googlebot's US-based requests too.

How do you confirm it with URL Inspection?

Confirm this status by finding the exact code Google received and whether your server still returns it. Google's own instruction is to "Try debugging your page using the URL Inspection tool."

1. Inspect an example URL from the report. Our URL Inspection tool guide explains each field.
2. Read Page fetch and Last crawl in the indexed result. Google notes that "All information shown in this tool is derived from this last crawled version" (URL Inspection tool help).
3. Click Test live URL. If the live test now succeeds, the error may have been fixed after the last crawl.
4. Check the code from outside Google with curl, as a browser and with Googlebot's user-agent string.
5. Check your server or CDN logs for real Googlebot requests and the status code each one got.

These are the checks we ran on October 17, 2026. First, how curl -I reports several 4xx codes from a public test service:

for c in 400 405 410 451; do curl -sI "https://httpbin.org/status/$c" | head -1; done

HTTP/2 400
HTTP/2 405
HTTP/2 410
HTTP/2 451

Then a comparison of a browser user-agent and Googlebot's documented user-agent string against one of our own pages:

URL="https://freshlycited.com/about"
curl -s -o /dev/null -w "%{http_code} browser\n" -A "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/130.0 Safari/537.36" "$URL"
curl -s -o /dev/null -w "%{http_code} googlebot\n" -A "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" "$URL"

200 browser
200 googlebot

Both returned 200, which is what a healthy page looks like. On an affected site, a 4xx answer for the Googlebot line only points to a user-agent rule. Two limits apply. curl -I sends a HEAD request, so re-test with a normal GET (drop -I) if the codes differ. And a request from your laptop isn't from Google's network: Google says the user-agent "is often spoofed" and that the best way to verify Googlebot is "a reverse DNS lookup on the source IP of the request" (Googlebot), so IP-based rules only show up in logs or in the live test.

How do you fix "Blocked due to other 4xx issue"?

Fix it by making each URL you want indexed return 200, and each URL you've retired return a clear, deliberate answer.

1. Group the example URLs by status code. One code across many URLs usually means one rule or one template.
2. 400 or 414: fix the internal links or templates producing the bad URLs, and shorten parameter-heavy URLs. Redirect bad URLs that other sites link to.
3. 405 or 411: check the app, framework or proxy rule that rejects ordinary GET requests, and test again with curl.
4. Firewall, bot or CDN rules: allow verified Googlebot. Google publishes the reverse DNS masks and IP ranges to match against, and its advice is to "identify which part of your website's infrastructure is blocking Googlebot and remove the block" (Search Console Help).
5. 451 or geo blocks: decide whether the block is legally required. If it is, the URL won't be indexed for the blocked region; if not, lift it.
6. Removed pages: a 410 or 404 is fine for content that's gone. If the content moved, use a 301 redirect instead. Remove retired URLs from your sitemap and internal links.

How do you validate the fix?

Validate by clicking Validate fix on the reason once every URL you care about returns 200, then re-inspecting a sample. Google says validation "typically takes up to about two weeks, but in some cases can take much longer" (Search Console Help).

• Expect retired URLs to stay listed for a while. Google "continues to crawl all known URLs even after they return 4XX errors for a while, in case it's a temporary error."
• Read the validation state. "Passed" means "All known instances of the issue are gone"; "Failed" means "A certain threshold of pages still contain this issue", so fix the rest and restart.
• Fixed pages may move to another status rather than straight to indexed; crawled - currently not indexed means Google reached the page and is still deciding.

When should you push the URL for a recrawl?

Push for a recrawl only after the URL returns 200 to a live test, and only for pages you want indexed. URL Inspection won't accept it sooner: you "cannot request indexing if the page is considered to be non-indexable in the live test" (URL Inspection tool help).

• A few important URLs: click Request indexing. Google says "there's a quota for submitting individual URLs and requesting a recrawl multiple times for the same URL won't get it crawled any faster" (Ask Google to recrawl).
• Many URLs: resubmit your sitemap with accurate <lastmod> dates.
• Then wait. Google says crawling "can take anywhere from a few days to a few weeks."

Our guide to submitting a URL to Google compares the routes. Across many sites, you can check which unblocked pages Google has indexed in one list, then push only the ones it still can't see. FreshlyCited re-checks each pushed link on days 1, 3 and 7, and an index credit is used only if the link gets indexed, and comes back after the day-7 re-check if it isn't (exclusions apply, such as pages that return an error or carry noindex). Its pre-flight check flags URLs that still return any 4xx or 5xx code first, so you can skip them for free. Google still decides what it indexes.

Unblocked your pages? Check them free to see which ones Google has indexed, and push only those it still can't see.
