If there is something wrong with the client application certificate created for the application, you may need to recreate it.
Using the UA Configuration Tool
This procedure assumes default setting for the instance store type and location. If your application uses different setting, you may have to modify the procedure accordingly.
- Download and install UA Configuration Tool.
- Run it.
- Switch to the "Manage Certificates" tab.
- Make sure that "Store Type" is set to Directory.
- In the "Store Path", drop-down the list, and select the path ending with "Machine Default". The, press the "View Certificates" button. This is the store for the instance certificates of the UA apps on this computer.
- Delete the certificates that belong to your application (right-click and choose "Delete"). If you know that it is safe, such as when there are no other OPC UA applications on the computer, you can even delete all certificates in this store.
- Restart your application, making sure it is done under elevated privileges (so that it has write access to the stores). This should re-create the app certificate and store it where it belongs to - if that was the cause of the problem.
