Blocked Due to Other 4xx Issue: How to Fix It

What "blocked due to other 4xx issue" actually means

"Blocked due to other 4xx issue" means Googlebot requested a URL and got a 4xx (client-side) response that Search Console doesn't already break out into its own category.

Because Google couldn't retrieve the page, it won't index it. In these cases, the URL stays out of search results until it returns a successful status.

The word "other" is doing the work here. Search Console already has dedicated labels for the three most common 4xx codes:

• ›401 → "Blocked due to unauthorized request (401)."
• ›403 → "Blocked due to access forbidden (403)."
• ›404 → "Not found (404)."

So "other 4xx" becomes the umbrella for everything else in the 4xx range: 400, 405, 408, 410, 429 and similar codes. The message is vague because Google knows a 4xx happened, but it's not one they have labeled.

Which 4xx status codes trigger this error

These are the codes that most often land under this label. You need to identify which one your server is actually returning before you can fix anything.

A note on 410 (Gone): if a page is intentionally removed for good, a 410 is the correct response and you shouldn't "fix" it. Just make sure it isn't a page you actually want indexed.

What causes 4xx errors for Googlebot

Most cases trace back to one of these five causes:

• ›Security rules and WAFs. Firewalls like Cloudflare, Sucuri or AWS WAF sometimes misidentify Googlebot as a threat and return a 403 or block the request. Security plugins on WordPress can do the same.
• ›Rate limiting (429). The server returns 429 when it decides too many requests have come in too fast, and Google won't index a page it keeps getting rate-limited on.
• ›Server or CDN configuration. A CDN rule, an .htaccess directive, or a template change can start returning a 4xx on URLs that render fine in your browser.
• ›Malformed URLs (400). A 400 means the server couldn't understand the request — often an incorrect URL structure or bad parameters. This is common with faceted navigation and session / tracking parameters.
• ›File permissions. Directory permissions set too tightly (e.g. 700 instead of 755) can trigger a 403.

A useful tell: because these are client-side responses tied to how the request is made, you often won't see the same error in your own browser — which is exactly why the report feels so opaque.

How to find the exact 4xx status code Google hit

Search Console tells you a page is affected but not which 4xx code it returned. You have to find that yourself. Work through this sequence:

1. ›List the affected URLs. In Search Console, go to Indexing → Pages, scroll to "Why pages aren't indexed," and click "Blocked due to other 4xx issue" to see the full list. These live under the Pages section → Not indexed tab.
2. ›Inspect a URL. Click a URL, then Test live URL in the URL Inspection tool. It shows exactly what Googlebot saw, including the HTTP response and any redirects.
3. ›Fetch as Googlebot. Because the error is often user-agent-specific, reproduce it with the Googlebot user agent. In Chrome DevTools, open the Network conditions tab, uncheck "Use browser default," and select "Googlebot Smartphone," then reload and read the status code. You can also run curl -A "Googlebot" -I https://yoururl from a terminal.
4. ›Check server logs. Logs show the real status code your server returned to Google's IPs, which is the ground truth when DevTools and the browser disagree.
5. ›Verify it's really Googlebot. If a WAF is blocking, confirm the requesting IP actually belongs to Google before you widen access, so you don't open the door to spoofed bots.

How to fix each 4xx error, code by code

Once you know the code, the fix follows from it:

How to validate the 4xx fix in Search Console

After fixing the root cause, return to the "Blocked due to other 4xx issue" report and click Validate fix.

Google will recrawl the affected URLs; recrawling corrected URLs typically takes a few days to a few weeks depending on crawl budget.

The report updates as Google re-attempts each URL, so recent fixes won't show instantly. Keep the URL Inspection tool handy to confirm each page now returns a 200 before you rely on the validation.

Finding 4xx-affected URLs at scale with SEOcrawl AI

Search Console shows the issue but makes you inspect URLs one at a time. SEOcrawl AI pulls your Search Console coverage data and surfaces indexation states across the whole site, so you can spot affected URLs in bulk instead of clicking through them individually.

Our MCP server lets you read the full index-coverage breakdown by state and filter crawled pages by status code (for example, everything returning a 404) directly from Claude or ChatGPT, and tag them by rules, manually, or over MCP. Pair that with scheduled crawls and alerts so you catch a spike in 4xx URLs before it dents your rankings.

Find every 4xx-affected URL in one place. Instead of clicking through Search Console URL by URL, SEOcrawl AI shows your full index-coverage breakdown and lets you filter crawled pages by status code straight from Claude or ChatGPT. Try SEOcrawl AI or explore the SEO Dashboard.

FAQs

What does a 4xx error mean?

A 4xx error is a client-side HTTP status, meaning the request itself couldn't be fulfilled: the page isn't found, access is refused, the request is malformed, or the server is rate-limiting it.

The 4xx family includes 400 (bad request), 403 (forbidden), 404 (not found), 410 (gone) and 429 (too many requests), among others. For SEO, any 4xx on a page you want indexed is a problem, because Google can't retrieve the content to rank it.

Are 4xx errors bad for SEO?

They are when they hit pages you want in the index. A page returning a 4xx can't be crawled, so it won't be indexed or ranked, and you lose the traffic it would have earned.

At scale, widespread 4xx errors also waste crawl budget and can signal poor site maintenance. Intentional 404s and 410s on genuinely dead URLs are normal; the problem is 4xx responses on pages that should be live.

What is a 4xx error in SEO?

In SEO terms, a 4xx error is any client-side response that stops search engines from accessing a URL. The ones that matter most are 404s (broken or removed pages), 403s (access blocked, often by a firewall) and the codes behind "blocked due to other 4xx issue" like 400, 429 and 410.

How do I find which 4xx Google hit?

Search Console doesn't name the code, so inspect it yourself. Open the affected URL in the URL Inspection tool and run Test live URL to see the response, or fetch the page with the Googlebot user agent (in Chrome DevTools' Network conditions panel, or with curl -A "Googlebot" -I [url]).

Server logs give the definitive status code your server returned to Google. To do this across many URLs at once, SEOcrawl AI lets you filter crawled pages by status code in bulk.
