renamed heroku app from website, now it's not found
The Answer by James Ward is also correct, alternatively try doing this:
1). open a terminal
2). Go to your_app_directory/.git/config
3). Once you open the config file then edit as follows:
Change
url = git@heroku.com:old_app_name.git
to
url = git@heroku.com:new_app_name.git
Obviously substituting your apps old name to its new name. Hope it helpsAlso checkout this link renaming from cli - heroku
