Windows Certificate Store not checked - WinSCP 5.13

2018-10-08 11:01

Hello everyone,
when I want to establish a connection to a WebDAVs-Server I get the message "Certificate not trusted / Dem Zertifikat wird nicht vertraut." The Root-CA and the Intermediate-CA of the certificate is stored in the Windows Certificate Store. So it looks like the Windows Cert. Store has not been checked. How can I provide the Root-CA to WinSCP?

Can you provide us a hostname of your server, so that we can test it?

Hello Martin,
thank you for your Reply. I get this message in General, Independent of the Server I choose. For example: I also get this message on Server winscp.net on port 443.

The Code Looks as follows.

"C:\Program Files (x86)\WinSCP\WinSCP.com" ^
  /log="C:\..\log\WinSCP.log" /ini=nul ^
  /command ^
    "open davs://winscp.net/ -rawsettings ProxyMethod=3 ProxyHost=""10.1.2.3"" ProxyPort=3128" ^
....
...
"close" ^ 
exit

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.

I set Debuglevel to 2 an got following message:

. 2018-10-12 08:01:21.895 Certificate failed to verify against Windows certificate store: Error: 80092013, Chain index: 0, Element index: 0

So I think the problem is the certificate revocation check of Windows. Windows has no internet-Access in this Scenario, so the CA cannot be checked for revocations of the Cert.
