Unable to add custom CA certificate for HTTPS scanning

We're using version 4.3.3.1 of the web appliance and when trying to upload a custom CA cert and key, receive an error that the file contains a virus and will not be uploaded.  I've tried uploading via the GUI, tried with cURL on the command line and even tried multiple CA cert/key attempts and all result in the same error.  Can anyone shed some light as to why this is happening?

  • Hi Matt,

    Can you please show us a screenshot of this error? The certificate must be in PEM or PKCS#12 format. A certificate must be a self-signed certificate that has been deployed to endpoint browsers, or by one of the authorities already supported by the browser on the endpoint.

    Thanks,
