Does anyone here have an email address (or web form address) for Cloudflare support?

I’m asking because increasingly often, Cloudflare-protected sites give me an endless loop:

Performing security verification This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot.

Verifying …

After a few seconds, a “Privacy” and “Help” link are shown next to the word “Verifying”. Then they all get replaced with a spinner icon, and the cycle starts again.

The help link goes to this page, which says:

You may encounter a challenge loop where the challenge keeps reappearing without being solved. This is in very specific cases where we detect strong bot signals. If you are a legitimate human, you can follow the troubleshooting guide below to resolve the issue or submit a feedback report.

Well, I am a human - even if my legitimacy is debatable.

The troubleshooting guide takes me here, which says:

Turnstile Failed Despite Passing All Checks All diagnostics passed, but Turnstile still couldn’t complete successfully. This is unusual and may indicate an edge case. … Since the local diagnostics did not find a clear cause, this may require investigation by Cloudflare.

• Copy your Session ID from the top of this page
• Click “Copy Full Results” in Technical Details below
• Share both with Cloudflare support

But it gives no contact details for Cloudflare support.

A web search turned up this page, but it only lists contact methods available for Cloudflare customers. I am not a customer.

Hence my question at the top of this post.
