Resolved SSH type seems disallowed on migration from WHM to Plesk

[MHC_1]

Server operating system version

Plesk

Plesk version and microupdate number

18

I know there are a LOT of SSH issues on here already, but they mostly seem to head back to sshd_config allow root login = yes.

This has been done.

My issue is this:

Failed to perform action: Fetch shallow data from source cPanel
Cause: Error while connecting to the the source server 'cpanel' (123.456.78.90) at '123.456.78.90' by SSH as 'root': Unable to connect to '123.456.78.90' by SSH: Bad authentication type; allowed types: ['publickey', 'gssapi-keyex', 'gssapi-with-mic'].
Ensure that the server is up and there are no firewall rules that may block SSH connections to the server,
then restart migration.
That is a critical error, migration was stopped.

This is root access using password on the Migrator Screen.

1) Does enabling 2FA on root Web interface login make a difference?
2) How do I set the SSH allowed types? SSH is already set up for the WHM server and requires a private key (for SFTP etc.) from the incoming user to access the server. Should this be disabled?

I am confused about the "keys" because the migrator at no part requests any authentication key from me for reachng the Cpanel/WHM server.

I got it to work :

In sshd_config change / ensure that :

PasswordAuthentication yes

...

GSSAPIAuthentication no
