Uploading via SFTP Uploading Issue

Hey all apologies if this is a commonly asked question, but I'm genuinely stumped and not a savvy SFTP/WinSCP person.

I currently have a dilema where I'm trying to upload a single file (it'll become multiple once I've got round this error), which is no more than 1MB. Originally I had a script executed within a C# application for FTP; worked like a charm. Since moving over to SFTP it has been nothing but issues.

Running the script from within my application, failed.
Running a script file via CMD, failed.
Manually typing it all in CMD, works.
Transferring the file manually via WinSCP, works.

My end goal is to get to how it was before, my app which is scheduled, transfers files as and when.. No manual input. I've done my best to look at other peoples issues and try see if their solutions would work for me, but no such luck as of yet. (Using ** to hide specific information)

Active session: [1] ***@***
C:\...\Pending\***.750 | 0 B | 0.0 KB/s | binary | 0%
Host is not communicating for more than 15 seconds.
Still waiting...
Note: If the problem repeats, try turning off 'Optimize connection buffer size'.
Warning: Aborting this operation will close connection!

Above is the error I've been facing constantly with the (unfortunately) unhelpful Error Code 4. The only relevant errors which could have been feasible were the uploading to a full system or exceeded user disk quote, but I've debunked these and can upload via WinSCP fine straight after an error from my own application.

Above is the error log I get client side, unfortunately I don't fully understand the issue from those logs so maybe some one can clarify on that part. I have limited access to the server so I'm unsure on what I could provide there.

Below is the script I'm trying to run manually from CMD, once cracked would transfer it to the application. Also as a side note, I've tried using .NET Assembly for WinSCP and get the exact same error, so at the moment I get the feeling it's Windows related.
open sftp://***!@***.***.com -hostkey="***"# -rawsettings SendBuf=0
put -preservetime -transfer=binary -resumesupport=on "C:\***\***\***\***.74*"
exit

Any and all help will be highly appreciated.

Re: Uploading via SFTP Uploading Issue

Please attach a complete session log file. As well as a complete session log file for "Manually typing it all in CMD, works".

GDPR Compliance and SFTP

Hi,

With the upcoming GDPR trauma, is using a plain text private key on a client server sending files to a public web server adequate to comply with this new law.

Thanks

Rob

I'm not a lawyer, but do not think that GDPR has anything to do with this.
