DNS subdomain no longer works nor redirects to anything

Moreover, kindly try to flush the DNS cache for the “CNAME” record just the domain hoprnet.org and then also for the sub-domain docs.hoprnet.org also with help of links below:

Cloudflare flush the DNS for “CNAME” record firstly for hoprnet.org and then for docs.hoprnet.org:
https://cloudflare-dns.com/purge-cache/

Google flush the DNS for “CNAME” record firstly for hoprnet.org and then for docs.hoprnet.org:
https://developers.google.com/speed/public-dns/cache

It could take up some time to refresh the records due to the TTL and/or DNS cache servers.
