Hi Shane,
I assume you're using the ServiceNow connectors from the Digital Exchange? If so, those are all implemented using the Web API feature of Blue Prism which does not support proxy authentication or NTLM at this time unfortunately. As an alternative, you could use the Utility - HTTP VBO that ships with BP (and is also available on the DX) to implement your calls to ServiceNow. You could actually look at the definition of the existing connectors within System -> Objects -> Web API Services to get the information about URL path, payload, etc.
Cheers,
