Nightly import error

We have a process that runs nightly which sends our zipped csv files to Canvas.  It recently stopped working.  I am getting the error: ERROR: Could not send file to Canvas.  The remote server returned an error: (401) Unauthorized.    

I did put in a case (04992331), but there has been no response.  I am not sure on how to connect with support?
