(401) Unauthorized., at System.Net.HttpWebRequest.GetResponse

Issue … Employee Directory (.wsp) in my UAT, QA, and Dev envs returns the following:

The remote server returned an error: (401) Unauthorized., at System.Net.HttpWebRequest.GetResponse() at NAMEOFWSP.COMPONENTSOFVISUALSTUDIOFILE.ExecuteQuery(String searchUrl, Int32& totalResults) No Profiles to Display.

I “environmentalized” all of the other .wsp’s to work in the three non-Prod envs with the exception of this one

As far as I can tell, I have matching permissions in each env with the corresponding -D, -Q, or -U svc acct
