Can't access through SSH key

[hushcoden]

I've created my keys (Ed25519) with puttygen, I've created a new user member of the 'admins' group and have populated its 'Authorized keys' field with the public key, but when I try to access via SSH, I get the attached error: can someone point me in the right direction ?

My bad, I have a new set of keys and it works !
