Unable to backup UCS configuration to SFTP site

[viby]

We have recently changed our SFTP server(Solarwinds) for UCS backup. The SFTP server usually works fine if we test direct uploads/downloads. However, the daily backup job throws an error complaining about access to the SFTP. 

Below are the FSM details for the upload task.

Remote Invocation Result:End Point Unavailable

Remote Invocation Error Code:1

Remote Invocation Description: End point timed out. Check for IP, password, space or access related issues.#

Name:Backup Upload

Status:Fail

Have seen this a few times an usually the remote server is incompatible/older due to SSH security enhancements removing support for older "vulnerable" versions/ciphers/kek/etc.

What model UCS FI and what version of UCSM software is running on it?
Is your solarwinds software up to date? What version?
With version specific details, then this may be able to be reproduced in the lab to see if this is a Cisco issue (and open a CDET) or a non-Cisco issue (like outdated solarwinds software).

I realize this is the other direction, but see: https://community.cisco.com/t5/unified-computing-system-discussions/unable-to-ssh-to-fi-but-can-browse-ucsm/m-p/4817690#M34452

With a Cisco TAC case, then TAC could access a bash shell under the hood to check `ssh -vvv user@solarwinds` command to see which side supports which SSH options.
