But with Valentina studio, even on the newest version I'm unable to connect. For auth I'm using public key and it is showing me exactly the same error:
Authentication by public key failed! SSH error: -18.
I'm 100% sure that connection settings are correct, checked and rechecked by eliminating any potential of human error.
So my assumption here is that Valentina is unable to connect because it uses old version of the ssh, does it use system ssh or is it shipped with one? Is there a way to point Valentina to the ssh executable I want it to use?
