WebDAV connection fails with WinSCP but works with Cyberduck

2018-06-01 07:44

I have a site that I can connect to via Cyberduck (webdav ssl) but the same site when trying to open via WinSCp is failing. I'm getting connection timed out message even though I have kept the connection timeout setting set to 120 seconds (I usually get the timed out message after about 15-20 seconds).

I have already seen https://winscp.net/eng/docs/faq_connection_refused and added WinSCP to firewall settings. Is there any other particular reason why WinSCP is blocking the connection?

I'm on
Windows 7
WinSCP 5.13.2

Thanks,
asprin

Cyberduck normally does not use CONNECT request for WebDAV.
Do know why it does in your session? Is there some proxy configured? Or some special settings?

Hi martin,

I'm sorry, I'm oblivious to that information. Is there a way I can find out if proxy is being used?

So this is what my proxy settings look like (see attached file)

I also tried unchecking "Use automatic configuration script" but that didn't solve the problem. Is there a way to configure WinSCP to use CONNECT as well?

If you uncheck that, does it prevent Cyberduck from connecting?

WinSCP cannot use automatic proxy configuration script.
You have to configure proxy manually:

Yes, it does prevent the connection. It appears that on unchecking it I'm not able to view/open websites too.

I also tried using that URL in the proxy settings of WinSCP

but got the following error (screenshot attached)

Am I doing it the wrong way?

I wrote that "WinSCP cannot use automatic proxy configuration script.".

Contact your network administrator to ask what proxy you need to use to connect to <sitename>.custhelp.com.

Yes, I realized later what you meant by that. Anyway, I just now solved it. I got the proxy address from the dat file that script was pointing too. And now WinSCP connects fine too.

Thanks for your help.
