I have downloaded Certify SSL Manager and trying to generate certificate for Exchange Server. My domain is autotomask.cz, but I need to add alternative names in certificate - primary domain is “mail.autotomask.cz” and alternative names “autodiscover.autotomask.cz, autodiscover.domain.local, mailserver.domain.local, mailserver”.
I ran the “request certificate”, but it produced this output:
2019-09-12 15:02:17.684 +02:00 [ERR] BeginCertificateOrder: error creating order. Retries remaining:1 :: Certes.AcmeRequestException: Fail to load resource from ‘https://acme-v02.api.letsencrypt.org/acme/new-order’.
urn:ietf:params:acme:error:rejectedIdentifier: Error creating new order :: Cannot issue for “autodiscover.peugeot.local”: Name does not end in a public suffix (and 2 more problems. Refer to sub-problems for more information.)
I am using IIS 10 and operating system is Windows Server 2019 Standard (virtual machine).
Can anyone give me an advise please, if it is possible to generate certificate (up to 5 domains?) for these alternative names?
Many thanks in advance.
