Git – SSH Fingerprint not authorized on Heroku after git restore

I had to restore my master branch from github a couple weeks ago and since then I've been receiving an error that states "Your key with fingerprint… is not authorized to access my app."

I've looked at the previous answers to this problem and have tried deleting the old keypair, creating a new one and uploading it.

I used the following posts and still get the same error:

Your key with fingerprint …. is not authorized to access… myapp. The remote end hung up unexpectedly. HEROKU, GIT CLONE

Why is my key w/ fingerprint not authorized when I try to push latest changes to Heroku?

Cannot push to Heroku because key fingerprint

When I run ssh -Tv git@heroku.com the terminal outputs the following:
