macOS does not support certificates with validity ending after year 2037

Certificates with a Valid To date of 2037 or later are not supported. It is not possible to parse a date variable from the Certification Authority on macOS. The Agent cannot connect, because macOS is unable to accept the Certification Authority.

1. Click Save to save your new CA. It will be listed in the Certification Authority list under Admin → Certificates → Certification Authorities, and will be ready for use.
