Hi there, I'm try to reverse proxy my Flint 2's admin page with a friendly secure internal URL (router.mydomain.com). I'm running Traefik on another machine, and it fails to obtain a certificate via Cloudflare DNS challenge: DNS call error: read udp 192.168.XX.X:XX->192.168.X.X:5053: read: connection refused [ns=192.168.X.X:5053, question='com. IN SOA']. As you can see I'm using AdGuard for DNS. Anybody have an idea how to allow this request through?
