HTTP Observatory "Scan In Progress" never finishes.

[ghost]

In scanning my site, the Scan In Progress bar appears, and never disappears. All the other tabs have results (mostly "A"). I have looked the net for what could cause this, and I don't see anything. The console output on my browser Web Developer says

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”), but I assume that is from one of your tests.... and not the issue. I am using Firefox 77.0

Any help? Anyone else see anything similar?

If your site is IPv6-only or TLS1.3-only, those are possible things that could interfere with the scan completing. Do either apply here?

[ghost]

No. IPv4 and TLS 1.2 and 1.3

Now, it says "Loading Results".... but still never returns. This is on the HTTP tab. The other three tabs work fine....

Anyone have ideas to help, or additional information you would like?

[ghost]

Can anyone help me get this resolved? I would greatly appreciate it. The site is IPv4 and TLS 1.2 and 1.3

Can you post the URL where this problem happens so it can be recreated?

[ghost]

Hmm.... Kind offer, but it's a private site that I do not really want to post, and it is also only up when I am testing. Is there debug information that might be helpful?

The only thing I can think of is setting up the project yourself and trying to recreate the issue.

I have a TLS 1.3 only site being handled by Cloudflare. Is this an intentional thing? Will it eventually support TLS 1.3 only?
