ENOTFOUND: getaddrinfo ENOTFOUND api.heroku.com api.heroku.com:443 Error for heroku create

The same was happening to me on Mac OS X 10.12.6 in iTerm2 3.1.5

Restarting iTerm solved the issue for me.

Carelessly, I don't know why, I tried several times of :

$ heroku create

It create succeed, with the logs:

Creating app... done, ⬢ still-harbor-32209    
https://still-harbor-32209.herokuapp.com/ |    
https://git.heroku.com/still-harbor-32209.git

So, I think try several times will solve it.

It means that the connection between api.heroku.com with a port of 443 and to your PC failed and results to shutdown. Thus retrying the command will succeeds.
