[Bug?] Regex filter not working properly.

[iAmSaugata]

Hi,
I was trying to access https://app.jasper.ai/signup/try-it-free from my Laptop and it failed to resolve the DNS, then I checked Adguard Hole log, and noticed it is getting blocked by one of my custom Regex, but in reality, there is no match with the actual FQDN app.jasper.ai.

/(^|[-.])(doh|dot|dns|rdns)[0-9]*[-.]/

Is this a bug?

Regards,
Saugata D.

@iAmSaugata, nope. It is because app.jasper.ai have CNAME record cname.vercel-dns.com:
https://www.whatsmydns.net/#CNAME/app.jasper.ai

Just exclude this host🙂

Thanks for the information.
