Cisco UCS backup fails after firmware update to SFTP/SCP serer v19.4.0.27 non supported algorithms?

My UCS backups now fail with "End point timed out. Check for IP, password, space or access related issues." 

My Cisco TAC case is telling me they only support backing up to openSSH that supports these Algorithms below. They are saying that Solarwinds SFTP/SCP v19 must not support  them. Where can i find out this information about SFTP server?
