Proxy request failed, can't connect through proxy server

2021-11-11 06:18

Hi there,

I am using WinSCP as a way to connect to one of our "ftpes://xxxxxx" clients and I am totally fine when I create the session and connect to the clients server using the front end app. But then when I "generate session/URL code" and then try to execute it I am getting the following error:

< 2021-11-11 18:05:43.277 Script: Connection with proxy established, performing handshake...
. 2021-11-11 18:05:43.277 Connection with proxy established, performing handshake...

Any ideas? As you can see I am using a proxy server as this is my way to get access using my working laptop but again, doing it from the front end using the proxy credential it works totally fine; the problem is while using the batch file.

These are my Raw Settings: (not sure if I should add / remove anything:

AddressFamily=1
LocalDirectory=C:%5CUsers%5CMyMachine%5CDocuments
RemoteDirectory=/Report
ProxyMethod=3
ProxyHost="REMOVED as NO REQUIRED"
ProxyPort=8080
ProxyUsername="REMOVED as SENSITIVE DATA"
FtpForcePasvIp2=0
SslSessionReuse=0
ProxyPassword="REMOVED as SENSITIVE DATA"

Any ideas? Cheers!

What do you by "REMOVED as NO REQUIRED" at proxy hostname? Proxy hostname is always required.

Please post complete session logs from both GUI and the script.

"Complete session logs from both GUI and the script", please.

Did you assembly your raw settings on your own? Or did you have them generated by the GUI?
