[X2Go-User] X2Go Client: Kex error : no match for method server host key alog: server [ssh-rsa], client [ssh-ed25519]

Hey everyone,
Any advice on the problem below?  I hit it consistently with X2Go Client, but it does not happen with the Pyhoca client.
Error:
Kex error : no match for method server host key alog: server [ssh-rsa], client [ssh-ed25519].
Client computer:
* Windows 8.1 connecting to Linux Mint 17.1 (Ubuntu 14.04.1) running the MATE desktop.
* X2Go client software v4.0.5.2.  The problem does not happen with the Pyhoca software (I downloaded the latest version).

Server:
Linux Mint 17.1 (Ubuntu 14.04.1) running the MATE desktop.

X2Go Server:
     Server Core:
        x2goserver (4.0.1.19)
        x2goagent (3.5.0.31)

    Server Extensions:
        x2goserver-extensions (4.0.1.19)
        x2goserver-xsession (4.0.1.19)

X2Go Server Add-ons:
        x2gomatebindings (0.0.1.3)

X2Go Server Features:
        X2GO_CLIPBOARD_MODES
        X2GO_LIST_DESKTOPS
        X2GO_MATEBINDINGS
        X2GO_MOUNTDIRS
        X2GO_MOUNT_UNCPATHS
        X2GO_PUBLISHED_APPLICATIONS
        X2GO_RUN_EXTENSIONS
        X2GO_SERVERSIDE_DESKTOPCOMMANDS
        X2GO_SET_KEYBOARD
        X2GO_UMOUNTSESSION_ALL
        X2GO_UMOUNTSESSION_ONLYPATH
        X2GO_XSESSION

Additional Information:
Usually I use X2Go without ssh keys, so just type in my userid & password when connecting to the Linux desktop.   This has worked fine.
When the problem above started to happen, I tried generating RSA keys on my Windows machine and transferred them to my Linux machine, but this didn't help.  I also tried with DSA and also ED22519 keys, but no-go on X2Go.
I installed Pyhoca and authenticate using my userid & password.  I can then connect to the suspended session that was originally created with the X2Go client.
For now I am using the Pyhoca client, but would also like to get the X2Go client working again.

Thanks!
