Immediate "Network Error: Software Caused Server To Abort, Will connect after clicking "Reconnect"
I have had a strange issue arise recently.
I had no prior issues connecting to this SFTP server but as of the 4/21/2020, I receive the "Network error: Software Caused Server to Abort". If I say ok and try again, I get the same error. If I click "Reconnect", sometimes it takes two clicks but it will connect to the server fine.
My environment: Windows Server 2008 R2.
WinSCP: WinSCP_release_5.17.4 (uninstalled and reinstalled today)
I have uninstalled/reinstalled an older version that was working prior as well.

I tried Filezilla to see if it would connect and it would not. I tried Cyberduck and it worked without error. I would prefer to use WinSCP.
Any thoughts as to why this is happening?
