Known issue. We have something similar on RPi3 and x86-64:
Arokhaerr I'm not aware of any noteworthy changes to the SSH server between LE12 and LE13 but perhaps delete any stored profile or connection in the app and recreate in case there are cipher changes. Using a normal computer, check SSH in to prove the SSH service is enabled/running and that password auth is allowed. If yes, perhaps clear any stored connection/profile in the app and recreate. We don't change certs after initial boot but the accepted ciphers can/do change over time (albeit not often).

SSH is definately working, maybe its an issue on android. Ill test some things and reply later.
