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
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.
