I changed the password for the OPC-UA Server Connection but left the username as default (opcuauser). The server immediately faulted with the following log items:
User “opcuauser” connected but could not authenticate. (invalid username or password)
Returning ServiceFault for request: com.inductiveautomation.opcua.types.messages.ActivateSessionRequest@51f9a8db. StatusCode=StatusCode[Severity=Bad, Subcode=Bad_CertificateIssuerRevocationUnknown]
I tried resetting the OPC-UA module, re-discovered the endpoint, and regenerating the OPC-UA certificates but none of these resolved the issue. I then changed the password back to default (password) and the server started working again.
What steps are required to change the password for opcuauser without faulting the OPC-UA server?
