I will be happy to help you.
From what you sent me, it looks like you have a problem setting up TLS over DNS with DNSSEC.
Perhaps you could try the following steps:
Check if your DNS server and port are set correctly. You can use nslookup or dig to verify that the DNS server is responding to queries.
Check if you have the DNSSEC certificate set correctly. You can use dnssec-keygen or dnssec-signzone to generate and sign the certificate.
Check if you have the correct SSL/TLS configuration on the server. You can use openssl or sslyze to test and analyze SSL/TLS connections.
Check if you have the correct configuration of SSL/TLS on the client. You can use schannel or tlsdiag to test and analyze SSL/TLS connections.
If the problem persists, it may be helpful to check the server and client logs for more information, or contact technical support for help diagnosing the problem.
I would also recommend checking the Microsoft documentation or forums for specific instructions regarding your situation, as the error may be specific to your environment and configuration.
