'Fingerprint has already been taken - Gitlab

I deleted my local Gitlab repository (using Ubuntu) and recreated it. Now I wanted to add a new SSH key so I don't have to type email/pw on every push. What I did:

ssh-keygen -t rsa -b 4096 -C "[email protected]"
ssh-add ~/.ssh/id_rsa

Then added the content of id_rsa.pub into the key form on Gitlab/SSH Keys. I deleted every old key in the settings and also every key in ~/.ssh/ before. And i still get the messages:

Fingerprint has already been taken / Fingerprint cannot be generated

git

Try first ssh -Tv [email protected] to double-check you are correctly authenticated.

Then check:

your deploy keys (Settings -> Repository -> Deploy Keys), as explained here.
your other GitLab accounts
