Vivaldi under macOS
The browser is available for different platforms (Android, iOS, iPadOS, macOS, Linux and Windows). Here we look at the settings under Apple macOS.
To access pages with Vivaldi that require "client authentication" with a certificate, a corresponding certificate must be imported. In the example we want to access the URL "https://vc.edv-workshops.com" (the address does not exist).
If you have not imported a certificate, the error message "400 Bad Request - No requirred SSL certificate was sent" or "403 Forbidden" will appear when the address is accessed.
