Git Push Error - Could not resolve host name

Simply type:

git remote -v

and double-check the url associated with origin for your upstream repo.

Once you have the right url, update your remote origin with another git remote command:

git remote set-url origin /the/right/url

In your case, the url is wrong:

https:/github.com/nkshastri/datasciencecoursera.git
# instead of:
https://github.com/nkshastri/datasciencecoursera.git
     ^^^^

Simply type:

git remote set-url origin https://[email protected]/nkshastri/datasciencecoursera

Then try again:

git push -u origin master

(with master, not maaster)

Sometimes this can be caused by a network issue. Try restarting your wifi or, if the repository is behind a VPN, make sure you are on the VPN.
