Are you able to establish a connection to that KepServer using another OPC UA Client (e.g. UAExpert) on the same node where your SW GW is?
When establishing communication between an OPC UA Client (SW Edge Gateway) and OPC UA Server (KepServerEX), it's a multi-step process if you don't manually move the certificates over.
- Make sure that you have your endpoint with
Encryption: Basic256Sha256 - Message Mode: Sign and Encrypt
enabled on KepServerEx (OPC UA Configuration Manager -> Server Endpoints tab) - Export the server cert: OPC UA Configuration Manager -> Instance Certificates -> Export Server Certificate.
- Trust the client: The certificate exchange happens automatically upon first connection (it will fail the first time, expected), but you can also do it manually.
- (Automatic) OPC UA Configuration Manager -> Trusted Clients tab -> click on the name of the client -> “Trust”
- (Manual) follow the steps here https://docs.aws.amazon.com/iot-sitewise/latest/userguide/enable-source-trust.html#export-opc-ua-client-certificate to generate your
aws-iot-opcua-client-certificate.pem
and import it in the 'trusted clients'
