You may input the host value in the wrong prefix of domain name. Mostly, when you input whole domain into Host Value of CNAME type. that domain will resolve to a Nested of its Domain name.
Example:
Domain: mydomain.tld
Type="CNAME
", Host="api.mydomain.tld
", Value="mydomain.tld
" TTL="1min";
→ "api.mydomain.tld.mydomain.tld
" will be resolved to "mydomain.tld
"
You should update to:
Type="CNAME", Host="api
", Value="mydomain.tld
" TTL="1min";
→ "api.mydomain.tld
" will be resolved to "mydomain.tld
"
