    You could try the way in this blog:https://www.spguides.com/the-remote-server-returned-an-error-407-proxy-authentication-required/
    After you run the code, you can restore these settings.

    Since you're using on-prem, it sounds like you have a pre-authentication proxy in front of SharePoint. You may need to bypass that proxy server if you're going to use credential-based authentication.
