Hello Guys, i have this issue with the OPC UA server, i have check the previous topics about this issue tried them with no result. Any Idea what might be the problem ? We had a power failure yesterday some systems went down.
That error states that your user was denied access to the server. Check all your authentication and user settings on the OPC connections and server configuration.
Hi David thank you for your reply. Can you guide me through step by step ?
If you're still in trouble you'd need to show your settings for both ends of the connection.
Post the error message - not an incomplete picture of it. Please see Wiki - how to post code on this forum.
