Problem

The currently installed certificate in the connector is expired and no longer valid.
Serrala does not provide certificates for connectors. The certificate must always be provided by the respective external provider.

    • In the status section, double-click on the relevant server entry.

  3. Check Installed Certificates

    • Review the list of installed certificates.

    • Double-click a certificate to check its validity status.

    • Identify the expired certificate.

  4. Import New Certificate

    • Click on Import Certificate.

    • In the popup, specify the file path of the new certificate (e.g., C:\Temp).

    • Confirm to load the certificate.

  5. Add Certificate to List

    • Add the imported certificate to the certificate list.

    • Save your changes.

  6. Restart ICM (Internet Communication Manager)

    • Open transaction SMICM.

    • Navigate to:

      • Administration → Exit Soft → Global
