Route 53 not responding CNAME and SRV in query for registered domains.

Here are a few suggestions that may help troubleshoot:

• Double check that the CNAME and SRV records are configured correctly in the Route 53 console. Make sure the name and type match what you are querying for.

• Verify the NS and SOA records are configured properly so the domains are delegated correctly to Route 53.

• Check if there are any firewalls, security groups or ACLs that may be blocking access to Route 53 for those record types.

• Try querying the CNAME and SRV records from different networks and locations to see if it is an localized issue.

• You can also try tools like digwebinterface.com to generate queries and debug DNS issues.

Also, consider

• Propagation Time: Changes may take time to spread globally.

• TTL: Ensure TTL isn't set too high, delaying changes.

• Query DNS: Use tools like dig +trace to trace resolution paths.

• Resolver: Confirm your DNS resolver isn't causing issues.

• Firewall/Network: Check for any blocks on DNS traffic.

• DNSSEC: Verify DNSSEC configurations if enabled.
