OS_CACERT was being added directly to the environment rather
than usercc_early. This caused an untrusted CA error to be
thrown.
Ensure that SERVICE_HOST is in the Subject Alt. Names of the
issued TLS server cert. The gate sets it to 127.0.0.1 which
wasn't being handled. Only the FQDN of the host and actual
IP address of the machine were being added.
