Broken Pipe during push - Github issue -

i'm new @ version control using github. everytime try push files repository created, receive following log:

"c:\program files\git\bin\git.exe" push -u --recurse-submodules=check --progress "origin" refs/heads/bruno.peixoto:refs/heads/bruno.peixoto counting objects: 1481, done. delta compression using 8 threads. fatal error: network error: software caused connection abort fatal: sha1 file '' write error: broken pipe fatal: remote end hung unexpectedly error: failed push refs 'git@github.com:brunolnetto/semestres.git' done 

i've followed beginners instructions seems it's not naive error i'm stumbling at. attention last 5 lines! happens either if try small project or big one. i'm struggling issue couple days , looked solution in numerous forums, without success . appreciated.

best regards, bruno
