[R-pkg-devel] Getting error: Installation failed: Unknown username with my package

I had a few week development hiatus with github.com/rmsharp/nprcmanager and when I tried to get a Travis build to work it failed. All of my local builds are working without errors or warnings, but the devtools::install_github(?rmsharp/nprcmanager?) fails with this error message

library(devtools)
install_github("rmsharp/nprcmanager")

Installing nprcmanager
Installation failed: Unknown username.

Two other packages of mine, one private rmsharp/renameSurgerySheets, and one public rmsharp/rmsutilityr both install fine.

Does anyone know what I may have broken or how?
