From the standalone server, or relay server in the Relay/Dependent scenario, copy
the CimScadaConfigRootCA.crt certificate available at [Install
location]\Proficy\Proficy CIMPLICITY\ScadaConfigPKI and on the Operations Hub
server, install the copied certificate under Trusted Root Certification
Authorities.
Once you have installed the certificate, open any browser and try to access the
relay server in the following format: https://<relay-server>:491.
On successful connection, you will see the Proficy Webspace page.
