Can't get my project into GitHub repository

I have moved it from the MBED Online Compiler environment to Keil and successfully compiled and run it in Keil.  I am following the recipe to "Convert to a GitHub repository".  It says I haven't connected to my GitHub account yet. In Keil I select "Connect to Github".  Nothing happens.  When I continue with the recipe it says "An error while creating <my project>".  Wise words would be appreciated!
