Cloudflare WARP causes DNS lookup failure
This URL fails when I have cloudflare WARP enabled

What would cause that?

One of their nameservers (ns2) is responding with expired dnssec signatures, causing occasional dns failures: https://dnsviz.net/d/bridge-club.org/dnssec/
Why it doesn't happen without WARP: Either because you were getting lucky and it retries/hits the working nameservers, or your default DNS which is most likely your ISP's DNS Resolver does not verify DNSSEC, which is very common.
