Hi @harishassuredpartners ,
Good Day!
- Please input the below command to check whether target system has TLS certificate installed or not.
openssl s_client -connect ip/fqdn of machine:TLS port
for example,
openssl s_client -connect 192.54.35.32:636 - Check the certificate details in command the command response.
- Check Subject and Subject Alternate Name (SAN) contains the FQDN of AD DC or not.
I am suspecting that the Certificate is not installed in the DC.
If certificate is there then try to install the new certificate with is fetched by using command present in step 1.
Also look into below topic for more clarification for installation steps.
Hope the above information will help you .
Thank you.
