I've downloaded my RSA private key into the app and configured a SFTP connection via IP and custom port to a VPS. When I try to connect I get "Wrong passphrase or invalid/unrecognized private key file format". I've turned on debug but nothing gets logged. I use this same private key on my mac to SSH to the same VPS.
I had to enter my pass for the key. I was a little confused as I didn't see the text at the bottom stating this. Thanks for putting that there though!
