SSH connection ignores RSA public key

Hello everyone,
I’ve installed Gitlab on a bare metal kubernetes cluster.
It is using Gitlab’s forked ingress-nginx.
While the platform is working correctly, I can’t connect to the instance through ssh.

I’ve added the public key to the instance, and when I try to connect it requests a password while ignoring the public key:

ssh -T git@redacted
The authenticity of host 'redacted (XXX.XXX.XXX.XXX)' can't be established.
ED25519 key fingerprint is SHA256:qOb2+WcneviI4hDqY0zYq2qtmUPI8UhxTSqkg0CjRXw.
This host key is known by the following other names/addresses:
    ~/.ssh/known_hosts:79: [hashed name]
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'redacted' (ED25519) to the list of known hosts.

I’m trying to figure out why Gitlab is not allowing me to connect with a PublicKey. I have tried ssh with verbose (ssh -Tvvv) and didn’t give any error:

ssh verbose output
Had to tweak output a little bit as I can't post more than 10 links
ssh -Tvvv git@redacted
