macOS / OS X does not support Certificates with expiry date January 19, 2038 and later. ERA Agent running on macOS / OS X will not be able to connect to ERA Server.
For all Certificates and Certification Authorities created during installation of ERA components, the Valid from value is set to 2 days before certificate creation.
For all Certificates and Certification Authorities created in the ERA Web Console, the Valid from value is set to 1 day before certificate creation. The reason for this is to cover all possible time discrepancies between affected systems.
For example, a Certification Authority and Certificate, created 2017 Jan 12 during installation will have a pre-defined Valid from value of 2017 Jan 10 00:00:00, and a Certificate Authority and Certificate created 2017 Jan 12 in ERA Web Console will have a pre-defined Valid from value of 2017 Jan 11 00:00:00.
