SSH does not work with Duo Mobile two factor authentication.
When trying to use the ssh bundled with textastic I cannot authenticate to machines that require two factor authentication using Duo Mobile. Even though the push-authentication step succeeds from Duo, I always receive the error:
Failed to authenticate - methods: (keyboard-interactive,hostbased)
The Duo Mobile authentication works fine for other ssh clients on iPad, e.g. blink shell etc, so it must have something to do with the implementation on textastic.

I would have to try to reproduce this on my own device. Do you know if there is something like a public demo server that I can use for this?
Duo does offer a free version of their 2FA solution, which is probably sufficient to reproduce.
