Password rotation on Linux and AIX servers failing

Hello everyone,

After reinstalling the resource brokers in our environment, I began noticing intermittent failures during automatic password rotations on managed Linux and AIX systems.

Error recorded in the resource broker logs and console:
"The connection was closed by the server. Make sure you are connecting to an SSH or SFTP server."

Error recorded in the managed systems' sshd logs:
"Jul 28 04:30:43 Server01 sshderror: kex_exchange_identification: Connection closed by remote host"

Both errors occurred at the same date and time.

Has anyone else encountered this behavior?
Could this be resolved using the "Enable legacy algorithms for SSH account management tasks" option found under Configuration > Privileged Access Management > Miscellaneous?
According to KB0017016, "The option Enable legacy algorithms for SSH account management tasks enables legacy encryption, MAC, and key exchange (Kex) algorithms that were previously enabled in Password Safe".

If anyone has experienced this, I would greatly appreciate any insights that could help me resolve the issue.

Currently I’m on version 25.3.
