Topic "Option to disable TLS/SSL certificate check (commonName)"

Author Message


I'm trying to use WinSCP in a development environment (e.g. to test webdav over TLS), where I do not have certificates with valid IP addresses or DNS names.

I'm now getting the following error message, when I'm trying to connect to a Webdav Server over TLS/SSL:
SSL certificate checks failed: Server certificate was missing commonName attribute in subject name

I would like to optionally ignore this failure and still continue to establish the connection. Or to set a checkmark under Advanced->Connection->TLS/SSL to ignore commonName mismatches.

WinSCP version: 5.6.1
Windows 10 x64

Description: SSL failure

You can set SessionOptions.GiveUpSecurityAndAcceptAnyTlsHostCertificate to bypass the certificate check.
