Kepserver certificate setup steps:

Open the Kepserver Configuration Manager, by right clicking on kepserver icon in the task-bar and then clicking on OPC UA Configuration.Image Added

Note down the security mode used by the Kepserver, this is one of the important query parameter.

Image Added

When the security mode is not None, the subscription or publish will fail for the first time, with the below message, this is expected behavior as the certificates are not updated in Kepserver.

The A-stack will generate the certificate files in the path "PKI/CA/{path provided in the query}" for example when we use above query, the certificates are saved in "PKI/CA/atomiton/certs" folder.

Image Added

Copy these certificates on to the machine that is running the Kepserver, and import these certificates in Trusted Clients tab of configuration manager.

Image Added

Go to the Run time tab of Kepserver and then reinitialize the server for the new settings to take place.

Image Added

Restart the subscription in AStack and it should start working this time.

Troubleshooting:

If we are still getting server not connected error even after certificates are imported and connectivity between the system running AStack and system running Kepserver is validated, then it might be firewall issues, try adding exceptions in firewall and test.
