I am trying to use `balena ssh` command to access into a container. I already put my public key into the preferences, but I am not able to connect to this container.  
I’m using the following command:  
`balena ssh UUID dev`

And it show me the following message:

```auto
user@ssh.balena-devices.com: Permission denied (publickey).
SSH: Remote command "host UUID" exited with non-zero status code "255"

Are the SSH keys correctly configured in balenaCloud? See:
https://www.balena.io/docs/learn/manage/ssh-access/#add-an-ssh-key-to-balenacloud
Are you accidentally using `sudo`?

```

Hello, are you using a production or development edition of balenaOS? Also, which version of the OS? If it’s a production version, you will need to copy the ssh public key into config.json as described here: [meta-balena/README.md at master · balena-os/meta-balena · GitHub](https://github.com/balena-os/meta-balena/blob/master/README.md#sshkeys)

We are using `Production balenaOS 2.107.23`. I am using balena-cli in Ubuntu x86, I tried with ubuntu arm and it works perfectly, my team use Mac ARM and works for them.

Actually If I access through ssh to an ARM server and use the same key (ForwardAgent yes) to run `balena ssh ...` it works.

It could be related to the SO on my side?
