    Hello there,

    How are you?

    Possible fixes to add to the script before replaying.

    web_set_certificate and add the website certificate details here.

    web_set_user("domain\\user", "password", "host:port");   add the user that should authenticate, so this can be done during the script replay.


    Before this, check which authentication is used, and add the user that has permission to authenticate.

    To discover this, the manual operation could be done first and capture the data creating a browser HAR File, then review the authentication steps in the HAR File, and use that information in the script so it can authenticate during the replay.
