Certification Authority - PKI: 2nd NDES server with HTTPS connection issues

Hi everyone,

I configured the second NDES\SCEP server for a Laboratory Certification Authority Infrastructure.

The second server is identical to the first one in terms of IIS, Regedit configurations, certificates assigned to the Local Computer and to the Local User and with the same templates as the first Server etc....

I normally access in HTTP from another server on the same network (Edge browser): http://fqdn.domain.com/certsrv/mscep_admin/, but if I try in HTTPS always from Edge https://fqdn.domain.com/certsrv /mscep_admin/ I receive an error message related to the certificate (see attached image). If I try from Internet Explorer and from the same source server in lan, I can start an encrypted HTTPS connection without errors.

Why? The first NDES Server in any case opens properly http and https SCEP URL from the Edge browser.

All the attached images show identical configurations for the two NDES nodes which are practically identical.

Can you help me?

Thanks in advance,

Alessio.
