  • Security software: why do I have to disable the HTTPS security scan?

    Show Hide

    Disabling the HTTPS security scan is necessary because security software (i.e. antivirus) creates its own certification service (CA) if the security scan is enabled and hides the server’s SSL in the certification service. As a result, the authentication of the SSL client will no longer reach the web browser.  Unfortunately, the cause of the error lies in the antivirus architecture, which cannot be changed by the software developer.

    In order to use ID-cards in computers with security software, you need to adjust the security software settings.
