Unable to use WinSCP to connect to XOS Switches anymore

Unable to use WinSCP to connect to XOS Switches anymore

Anyone else having trouble using WinSCP to connect to XOS switches?
Unfortunately I haven't had to connect for some time, so I cant pinpoint when it stopped working.

Windows 10 running WinSCP 5.13.4 (Build 8731)
- checked Windows firewall
- turned off "Optimize the connection buffer size"
- returns "Host is not communicating for more than xx seconds. Still waiting..."

Connecting to:
System Type: X670G2-48x-4q
ExtremeXOS version 21.1.5.2
SSH Secure-Mode : On
- No errors displayed in the log file
- Can SSH in from same PC with no troubles

Hoping someone else has already stumbled across this.
Regards,

Looks like imported settings from Putty had a specific setting which caused the issue.
I just created a brand new session for the device using the defaults (including "File Protocol: SFTP"), which seems to work.

Grabbed this out of the WinSCP log file, looks like there's an error at the CLI prompt causing the issue.
