SSL Certificate Error in the Browser

Problem

While accessing Datameer server via SSL, one may get a certificate warning such as "This server could not prove that it is <IP_Address>; its security certificate is not trusted by your computer's operating system. This may be caused by a misconfiguration or an attacker intercepting your connection."

Cause

There is a mismatch in the domain that browser is accessing and the server-side certification is issued for.

Troubleshooting

Check the certificate using a command such as:

openssl x509 -in <Domain_Name>.cer -text -noout

and make sure that domain displayed in Common Name (CN) matches that is entered in browser URL.
