Limitations & Troubleshooting

Limitations

The current implementation of OPC UA does not provide the following features:

  • Registration of the server on local discovery servers (LDS)
  • User authentication using the X509 certificate
  • Communication with OPC UA client via HTTPS

Troubleshooting

Issue: Unable to connect the OPC UA client to the OPC UA server via a secure connection. All the necessary security certificates were added to repository as "trusted", but the client returns the BadInvalidTimestamp error.

Solution: Synchronize time between the client and server computers.
