Server down, need to download files, can't get logged in with WinSCP

Hello, I am in a desperate situation as I am unable to make a network connection with the server. I can use another SFTP app, I can ping, but I can't get WinSCP to connect. I really need the ability to use WinSCP's explorer style ability to download to Windows folders.
I have checked through all the troubleshooting steps I could find:

1. I know the IP is correct, as is the port
   
2. I know SFTP is the correct protocol
   
3. I expanded the timeout parameter
   
4. I disabled the firewall
   

The server is a CentOS/cPanel server, but since it won't boot, support set up a rescue disk that runs Debian 9. I used WinSCP ages ago and love the product. It is also the product that support suggested I use, but they won't help me getting it to work.
A solution is worthy of a PayPal donation, hint, hint!

Please post log files both from WinSCP and the other SFTP client that works (both from the same local machine).

The hosting company helped me out by downloading the files for me and giving me links to each one. I will ultimately want to get WinSCP working, but for now, getting the server back running is my priority. Thanks...
