Exception when browsing an OPC UA Server

01 Oct 2023 17:04 - 02 Oct 2023 08:08 #12264 by support

Very good that now you have the Administer OPC UA Application dialog integrated.

1. Please also include screenshot of the "Application Certificate" tab of the dialog.
2. Please also include screenshot of the "Application Manifest" tab of the dialog.
3. Are you able to connect when you answer "Yes" to the notification? If not, is the exception in "Browse for OPC-UA Data" different between the Yes and No responses - and what are the 2 exceptions in these cases?
4. On the "Trusted Certificates" tab, select the second row (the one with "GTCHVE3SA01 OPCUA Server". Then, click the "Trusted" item under "Trust Status" in the action pane on the right side. The "Trust Status" column for that certificate should change to "Trusted, Issuer". Exit the dialog, exit the application, and start it again. Is the problem resolved now? If not, are you getting the same symptoms, or is the behavior now different? If it is different, please describe the new behavior.

We have implemented Quick OPC version 2023.1. Now we have the Administer OPC UA Application option available,
The customer still getting an exception when using our software. Using UA Expert there is no problem.
As you can see the 2 EBI OPC server certificates are trusted in the Trusted Certificates tab.
See the attached screen captures.

Your advise is mostly appreciated.

Thank you.
