All of these indiscriminate cloudflare blocks (d3nn82uaxijpm6.cloudfront.net in particular) are blocking content on any website that host it's assets on cloudflare (in my case strava.com)

I came here to report the same issue, and I can reproduce the screenshot above. The problematic block is d3nn82uaxijpm6.cloudfront.net. This domain serves JS for strava.com when logged in to Strava.

Whitelisting the domain does fix the problem.

@mkasberg Hello. AdGuard DNS is not blocking this domain at the moment. Do you have only the AdGuard filter enabled, or do you have third-party filters as well? I see that this domain is blocked for example in CHN: anti-AD filter .

It seems to be removed from the block list now.

I use this list here:

https://v.firebog.net/hosts/AdguardDNS.txt

Which is just downstream of this project.

I guess it was removed at some point!

I noticed it was included on the 02FEB24 blocklist at https://v.firebog.net/hosts/AdguardDNS.txt and it was removed on the 05FEB24 blocklist.

I suspect it's been fixed upstream since it's no longer present -- if it's still present on other blocklists, like CHN: anti-AD filter, it might be the case that those blocklists have not yet been updated with the upstream fix...

Since it's not currently present in the blocklist I was worried about, I think that the issue's probably resolved...

If it loads fine now - then I will close it. Thanks for letting me know!
