for some reason bitdefender keeps producing this with dns over https enabled on firefox 105.0.1. If I browse that url on a machine without bitdefender is throws an error too about the cert.

firefox.exe attempted to establish a connection relying on an untrusted certificate to mozilla.cloudflare-dns.com. We blocked the connection to keep your data safe since untrusted certificates are issued by unrecognized Certificate Authorities.

I can add an exception but the cert on this size seems to be invalid. Any ideas?

After digging further I see that OpenDNS/Cisco Umbrella might be blocking the request too.
