When the Web Services URL is specified while adding a server in the WCC configuration tab, validation fails with the following error:
Error: E190098 PRD_SP7 (web services validation) - A connection exception was encountered: Certificate for <user01-I10279.xyz.com> doesn't match any of the subject alternative names.
This error is due to the SSL certificate exception for the hostname mismatch.
Verify the system hostname and specify the value in the Web Services URL. If it does not work, find the hostname using the Fully Qualified Domain Name (FQDN).
