disconnected: failed to negotiate host key algorithm
Is there a solution?
For you log, it appears the server supports RSA and DSS host keys, the two oldest and most common ones.
But Absolute can be configured to use (or not use) a host key algorithms, and the client and server will negotiate which one they both agree to use.
See the attached image. Under the SSH2 settings, you'll find the host key algorithms that are supported and which are disabled (below the line).
If RSA or DSA are disabled, enable them. If your screen looks like the image attached, we'll have to go to plan B
