Whenever this randomly happens to me, removing and adding heroku again as a remote reference always works.
每当我随机发生这种情况时，再次删除和添加 heroku 作为远程引用总是有效的。
First check if you do have heroku as a remote.
首先检查你是否有 heroku 作为遥控器。
git remote -v
git remote -v
If heroku is present, remove it.
如果 heroku 存在，请将其删除。
git remote rm heroku
git remote rm heroku
Then add it back.
然后再添加回来。
git remote add heroku [email protected]:project.git
git remote add heroku [email protected]:project.git
Usually this works with me, try it and let me know what happens.
通常这对我有用，尝试一下，让我知道会发生什么。

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.
尝试从终端退出，启动一个新的终端（命令行）进程并转到相应的目录，然后再次尝试推送到 heroku master。
I had encountered an error similar to yours :-
我遇到了与您类似的错误：-
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.
我做了上面提到的同样的事情，对我来说效果很好。我希望它也适用于你。

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:
如果您已经使用 ssh 从 git 连接了任何其他远程，那么您必须仅使用 ssh 连接 heroku 远程。要检查远程连接方式：
git remote -v
just remove https remote of heroku, connect again with ssh remote. like:
只需删除heroku的https远程，再次使用ssh远程连接。喜欢：
git remote add heroku [email protected]:<yourProject>.git
It should work.
它应该工作。
