communication error: Error connecting to TCSDeployServlet: Connection returned with 401 (Unauthorized)

Hi ,

We upgraded our NWDI System from 7.31 and facing an issue in defining the runtime systems for the track and saving them. We are able to save the track without any runtime definition but when there is one provided the track is not saved with the below the error message

communication error: Error connecting to TCSDeployServlet: Connection returned with 401 (Unauthorized)

Kindly any suggestions

Thanks
