Issue with push

I have created the project on gitlab UI. I able to clone,add,commit but while trying to push it shows the following error

    neelaveni@ltsp64 17:42:32$ git push -u origin master
    Counting objects: 3, done.
    Writing objects: 100% (3/3), 283 bytes | 0 bytes/s, done.

I have refereed the #44 (closed), as per the link I tried but even though I have received the same error. Kindly say the solution to resolve it.
