no connection to iLO 4 via PuTTY since SPP upgrade to version Gen9.1 (iLO 2.81)

[Eric_FELLOUS]

Hi,

the 6 HPE servers of my client are ProLiant Gen9 : DL360 (4 servers) and DL380 (2 servers).
These servers, that I installed OK in 2018, were under factory default iLO version 2.55.

During years and years it was possible to connect to iLO via PuTTY (versions 0.76 from Windows 10,  0.78 from Windows 10 and 0.83 from Windows 11).

Some days ago I upgraded SPP of these 6 servers to last available version : Gen9.1 (released 15/Sep/2022) ==> iLO 2.81

SPP upgrade were OK and the 6 servers (under RHEL 7.9) are running fine.

https access to iLO (2.81) is OK.

iLO (2.81) access to a server via RHEL 7.9 ssh from one of the other 5 servers is OK.

But impossible via PuTTY (version 0.83 from Windows 11) : Remote side sent disconnect message type 11 (by application): "Client Disconnect".

Do you know how to solve this issue ?

Best Regards,

Eric
