I have a few apps on Heroku, nothing has had this problem but I suddenly have had issues running git. Now I can't deploy my app to Heroku. When I run

git push heroku master

I get the following:

fatal: unable to access 'https://git.heroku.com/<herokuappname>.git/': Could not resolve host: (nil); nodename nor servname provided, or not known

When I run

git remote -v

I get the following:

heroku  https://git.heroku.com/<herokuappname>.git (fetch)
heroku  https://git.heroku.com/<herokuappname>.git (push)

I've looked up everything. Please help, thank you.

  • Did you checked [this thread](http://stackoverflow.com/questions/18290822/why-does-git-fetch-fail-with-could-not-resolve-host-nil-with-https-git) ? It's not heroku-related, but also has issues with not being able to connect to git repo, which seem to be root problem. – Dariusz Aniszewski Feb 21 '15 at 10:57

Whenever this randomly happens to me, removing and adding heroku again as a remote reference always works.

First check if you do have heroku as a remote.

git remote -v

If heroku is present, remove it.

git remote rm heroku

Then add it back.

git remote add heroku git@heroku.com:project.git

Usually this works with me, try it and let me know what happens.

    Didn't work for me , heroku git:remote -a , taken from http://stackoverflow.com/questions/5129598/how-to-link-a-folder-with-an-existing-heroku-app did the job. – Ohad Dahan Sep 23 '16 at 13:30
  • Same with me I pulled a repository and I had to add: heroku keys:add first and then do heroku git:remote -a – trickydiddy Oct 26 '17 at 14:13
  • This method doesn't work on my terminal. $ git push heroku master master ssh: connect to host heroku.com port 22: Connection timed out fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. – stevezkw Apr 22 '22 at 08:02

Try this:

git remote -v

git remote add heroku git@heroku.com:project(full url).git

These steps worked

Try exiting from the terminal, start a new terminal (comand line) process and go to the appropriate directory and then try to push to heroku master once again.

I had encountered an error similar to yours :-

fatal: unable to access 'https://git.heroku.com/<herokuappname>.git/': Could not resolve host: git.heroku.com

I did the same thing as mentioned above and it worked out well for me. I am hoping that it will work for you as well.

  • This solved my problem. I was really confused because ping and Chrome worked fine. Apparently my old terminal sessions were using a closed socket (i.e. `$SSH_AUTH_SOCK` variable had changed). – TastyWheat Feb 06 '19 at 17:34
  • @TastyWheat: If it helped, would be awesome if you could upvote my answer. Thanks. :) – Pavan Vasan Feb 12 '19 at 07:37

I was able to solve this issue by logging into heroku with heroku login

One of the main causes of that error is simply a bad internet connection, If you come across issues like this, simply changing your internet connection or using a better option fixes this problem.

This worked for me in the following order

git remote rm heroku
heroku login
heroku git:remote -a <app_name>
git push heroku master

If you have already connected any other remote from git using ssh then you have to connect heroku remote with ssh only. To check how remote connected:

git remote -v

just remove https remote of heroku, connect again with ssh remote. like:

git remote add heroku git@heroku.com:<yourProject>.git

It should work.

This worked for me

  1. heroku git:remote -a app-name
  2. git push heroku master
