HPE 5120 switch backup fails after IMC 7.2 to 7.3 upgrade

[PierreP59]

Hello,

After updating IMC 7.2 to 7.3.
The backup of HPE equipment no longer worked, after re-enabling sftp server enable on the equipment, everything was ok again.
Except my HPE 5120 swicthes, IMC manages to save running config but cannot save startup config.
the result for startup config is SSH authenticated failure, while the SSH account is the same for both.
looking at the log file the problem appears when trying to perform /H3CCommon/enter_sftp_exec.tcl, error message FATAL.

Do you know if there is a trick or if the problem is known?
Is it possible to have a specific adapter for the 5120 and not a generic adapter.

Thank you in advance.
