Troubleshooting OPC UA HDA Server Issues

Unable to Connect to the Server

Issue: When you attempt to connect to the OPC UA HDA server from an OPC UA HDA client, a message appears, stating that you cannot connect to the server.

Diagnostics:
  • Ensure that user authentication for the OPC UA HDA server is based on either user credentials or certificates. Anonymous authentication is not supported.
  • If you have selected authentication based on user credentials, ensure that you have entered the correct credentials of the Historian server.
