I've been working with Microsoft Orchestrator 2019 and have connection with SharePoint through Http protocol when i tried to change URL to HTTPs I'm getting the below error. I have checked and ensured that both ports 443 & 80 are opened between on-prem SharePoint and Orchestrator servers.

    Hi,

    The error (401) Unauthorized typically indicates an issue with authentication. When you switch from HTTP to HTTPS, the authentication method might need to be adjusted. Here are a few things you could check:

    1. App Authentication: If you are using App authentications, you may get the “The remote server returned an error: (401) Unauthorized.” message when trying to connect. Check if your tenant settings “DisableCustomAppAuthentication” is set to true. If yes, make it false.
    2. Kerberos Authentication: There could be an issue with Kerberos authentication. You might want to look into this and ensure it’s configured correctly.
    3. Authentication Providers and Bindings in IIS: Check the authentication providers and bindings in IIS.
