Replied by support on topic Certificate has is expired or not yet valid

Hello.

I think that the error message is quite clear. The OPC UA application instance certificate has expired.

If you have created the certificate by yourself, repeat the procedure and generate a new one.

If you are relying on automatic certificate generation provided by QuickOPC, you need to delete the existing certificate from the certificate store, and QuickOPC will generate a new one. In this case, the certificate will be in the directory in the file system (opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ry%20Certificate%20Stores.html ) so you can delete it from there (but beware there are multiple files - see the documentation). It might be easier to use the UA Configuration Tool - download it from this page: kb.opclabs.com/Tool_Downloads . More information: kb.opclabs.com/UA_Configuration_Tool_Overview .

If you need more detailed instructions, let me know.

Best regards
