WPF ASP.NET app not authenticating against SharePoint SITE. RRS feed

  • Question

  • Hello,

    We have a custom MVVM WPF application that is working against clients SharePoint API. This application has been working for months/years. Lately, first in UAT and then in Production the app could not authenticate, throwing this error:

    The request was aborted: Could not create SSL/TLS secure channel

    We have no access to their server, but I need to know why this could be happening(I need to help them solve this) - the application is working IF they are using it within their network. We can authenticate to the site when using browser.

    Thank you.
