I am a normal, real person trying to browse Stack Overflow from home. No weird office network issues or etc. No bots. A normal number of requests.

Every Stack Overflow page is blocked due to this Cloudflare CAPTCHA and I cannot use the site. The checkbox will not verify me. Meta Stack Overflow is blocked too so I can't investigate a solution. This blocks every SO Q/A page I hit from the SERP, making the entire site completely useless.

I'm using macOS + Safari. I'm possibly using (or have used in the past) Apple's new built-in iCloud Private Relay feature, although looking at the setting now it appears to be off.

The site loads fine using FireFox on the same machine.

I've used the Safari action "Reload Without Content Blockers" to reload the page without any extensions or scripts. Same issue.

I've logged in to SE here on Meta, which does not have the same issue. That login does not fix the issue on SO.

Console shows the errors:

Failed to load resource: the server responded with a status of 429 () https://meta.stackoverflow.com/

Failed to load resource: the server responded with a status of 429 () https://meta.stackoverflow.com/favicon.ico

Failed to load resource: the server responded with a status of 429 ()Blocked a frame with origin "https://challenges.cloudflare.com" from accessing a frame with origin "https://meta.stackoverflow.com". Protocols, domains, and ports must match.

I would investigate that "protocols, domains, and ports must match" issue but that question on Stack Overflow refuses to load.

This is incredibly annoying. How can I use Stack Overflow?

    Do note that the RayId is safe to share and actually helps diagnosing the issue. You make it easier if you copy / transcribe that in your post and/or contact us ticket if the issue doesn't get resolved here.

    http status code 429 is too many requests, which seems odd.

  • Is Safari running any userscript? IIRC safari doesn't support that but just checking in case that has changed.

  • I've used "Reload Without Content Blockers" which should shut down any extensions/userscripts. Not sure exactly what Safari supports.
