はじめ：

heroku git@heroku.com:ibhiroba1-0403.git (fetch)
heroku git@heroku.com:ibhiroba1-0403.git (push)
origin git@github.com:HOkn/ibhiroba1.git (fetch)
origin git@github.com:HOkn/ibhiroba1.git (push)

➜ ibhiroba1 git:(bugfix) git remote add heroku git@heroku.com:testhiroba.git

	This is the solution if you cloned the repo. –  JGallardo Sep 24 '13 at 6:01 Thank you! It works like charm :) –  Romans 8.38-39 Sep 8 '14 at 6:21 add a comment

問題：これをしたらエラー：

git push heroku bugfix:master
remote: ! Heroku has temporarily disabled this feature, please try again shortly.
remote: ! See http://status.heroku.com for current Heroku platform status.
fatal: unable to access 'https://git.heroku.com/ibhiroba1-0403.git/': The requested URL returned error: 50

なのでもう一度git remove heroku をしてheroku add domain をして pushしてみると：

! Heroku has temporarily disabled this feature, please try again shortly.
! See http://status.heroku.com for current Heroku platform status.

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
