when I add my machine, it says

[abbysdu]

Unable to authenticate session

I have the same problem. The server output log:

dropbear[10511]: Exit before auth (user 'root', 0 fails): Disconnect received.

This may be the issue of new connections need confirmation by interactively replying "yes" on the client. Client needs to add an option StrictHostKeyChecking=accept-new to auto accept that.

thanks! I solved it after add an option StrictHostKeyChecking=accept-new in client config.

Where do we need to add StrictHostKeyChecking?

I can't connect anywhere at the moment
