DoH URLs for security and family DNSes provided on this URL are incorrect
https://developers.cloudflare.com/1.1.1.1/1.1.1.1-for-families/setup-instructions/dns-over-https/
https://security.cloudflare-dns.com/dns-query/
https://family.cloudflare-dns.com/dns-query/
They doesn’t work because of / at the end of URL - server redirects requests to 1.1.1.1 main page.
If I delete / at the end of URL, everything is ok.
