[Bug]: unable to connect to hosts via ssh

[smindorf]

Current Behavior

I'm unable to connect to hosts via wsh.

wsh ssh root@host

Errormessage:

Known Hosts Key Missing (55s)
The authenticity of host 'xxx:22 (xxx:22)' can't be established as it does not exist in any checked known_hosts files. The host you are attempting to connect to provides this ecdsa-sha2-nistp256 key:
xxx=.
Would you like to continue connecting? If so, the key will be permanently added to the file /dev/null to protect from future man-in-the-middle attacks. 

When I click "OK" next error appers:

`Disconnected from "root@xxx"

error: Connecting to root@xxx, Error: ssh: handshake failed: Canceled by the user`
