Can't connect to my SSH server

Hello all!
I’m trying to make a small home server but I have problems setting up an SSH server.
On the server I use ubuntu-server on the client-side it is Manjaro. I want to be able to connect only with keys and not with passwords!

Now when I try connecting to the localhost on the server it works just fine, but after copying the generated public key to my Manjaro machine and trying to connect it just throws “Permission denied (Public key)”

After looking around the internet I found that by using -v I can find out more, so I’ll be sharing it’s contents

Any help on how could I resolve this would be much appreciated!

On Ubuntu machine:

(ubuntu) $ cat ~/.ssh/id_rsa.pub

… and check if this key exists in Manjaro authorized keys:

(manjaro) $ cat ~/.ssh/authorized_keys

it does. If I’m correct, the ssh-copy-id puts it there.
