Hi @dash,

I could not find in the documentation any reference about adding a CNAME to “[ssh.devices.DOMAIN.com](http://ssh.devices.DOMAIN.com)”.

Can you please point where this is explained?

I have this issue [https://forums.balena.io/t/error-ssh-to-device-via-balena-cli/4855](https://forums.balena.io/t/error-ssh-to-device-via-balena-cli/4855)

Not sure if related.

Thanks
