HTTP 403 · Forbidden

403 Forbidden.
Why are you blocked?

A 403 means the server understood your request but refused it. It's not always your fault — WAFs, geo-blocks, IP bans, and misconfigured permissions all cause 403s. Paste the URL below and get the real cause.

// 403 vs 401 — What's the Difference?

You're not logged in or your credentials are wrong. Logging in might fix it. The server is saying "prove who you are."

The server knows who you are (or doesn't care) and has decided you're not allowed regardless. Logging in will not fix a true 403.

Many Cloudflare / AWS WAF blocks return 403 with an HTML challenge page. The giveaway: check for a CF-RAY response header. LinkAutopsy detects this automatically.

// How to Diagnose Your 403

Switch to mobile data (4G/5G). If it works, your IP or ISP is blocked — not the URL itself.

Use the comparison button above. If Googlebot gets a 200 but your browser gets a 403, it's a bot-detection rule blocking real users — a serious misconfiguration.

LinkAutopsy shows all response headers. A CF-RAY header = Cloudflare. X-Cache: MISS = CDN miss. These tell you where in the stack the block is happening.

Paste your LinkAutopsy report URL in the support ticket. It gives hosting support the exact HTTP status, headers, DNS, SSL, and a screenshot — everything they need without back-and-forth.

// FAQ

Not usually. Most 403s are configuration issues — wrong permissions, an overzealous WAF rule, or an IP block. A hack would more typically cause a 500 or serve unexpected content.

A browser extension (VPN, ad-blocker, privacy tool) is likely modifying your request headers in a way that triggers a WAF rule. Disable extensions one by one to find the culprit.

Only partially. You can try a VPN, different browser, or mobile data. If the site is intentionally blocking you, there's no technical fix — contact the site owner.
