Issue with .NET Automation Connection
I am currently experiencing an issue where WinSCP is able to connect to our FTP server within the GUI, but we cannot get the same results using .NET automation. When I connect and export the session code it seems to match what I have scripted, I can't use the generated code exactly as I get a syntax error I believe stemming from the fact that I am using PowerShell 5.1 and not a later version. If I connect successfully using the GUI and then export the session I get the attached output when exporting to PowerShell (password has been removed), However, when I try to run the below script, which I think is functionally equivalent, this includes the port which my export didn't but leaving it off seems to get the same, I get this error connecting:
The user and password end up set the same, I'm wondering if it is related to the certificate in some way as at times I do get prompts using the GUI that I it does not trust the full chain of the TLS certificate for FTPS.
Connection failed.
Requested action aborted: internal error in processing.
