I'm new to github and GitHub Desktop and the web interface is all I'm familiar with. We've had various reports of this failing due to other tools being installed alongside, like anti-virus programs.

As j-f1 suggested, see what else you have installed that might be interfering. As a workaround, you can revert to the classic OpenSSL behaviour by opening the repository in a shell and running these two commands. I'm no PKI expert but doesn't the fact that IE can connect on the same machine suggest that the issue isn't tied to the certs themselves? Sometimes there is a long timeout like above but the majority of the time the error comes back pretty much instantaneously. This mailing list thread has some additional context :.

When curl is built with the WinSSL schannel SSL backend certificate revocation checking is enabled by default and the checking is handled automatically by the Windows OS, not by libcurl. I've had some reports of this but not enough details to recreate the issue on my end - whether it's related to something installed on the user's machine or something on the network isn't clear to me.

The revocation function was unable to check revocation because the revocation server was offline. The error message suggests something is blocking SChannel checking if the certificate has been revoked, which is part of the normal handshake process to let administrators blacklist certificates.

Whatever proxy settings you are using in libcurl will not be used to retrieve the revocation resource, instead the OS will use its settings. Assuming those settings are correct that error message usually means what it says, the revocation server is offline. This might seem a bit silly to ask, but how often is this occurring for you in the logs? Could you share the full logs so we can see if there's any chance the revocation server wasn't offline while you were using this?

I applied the registry setting that re-surfaces the warning when this happens and lo and behold I get the notification in IE now after a long pause which I assume to be the same 60 second timeout as was shown in the logs I posted above. So, it would seem that the revocation server isn't reachable in either case, even though IE makes it look otherwise. The version I was using previously worked without issue, presumably because it wasn't checking for revocation?By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Update : If you're using self-signed or corporate certificates on your own git server, and you get an error when attempting to connect to it such as self signed certificate in certificate chainor SSL certificate problem: unable to get local issuer certificatethen the solution is to tell git where to find the CA that was used to sign that site's certificate.

You can do this with the following configuration command:. This is a more robust solution compared to adding your CA certificate to git 's bundled ca-bundle. This error is also commonly hit when you're on a corporate network that performs MITM on all traffic, and then blocks the revocation check. While, obviously, the ideal situation is to not block the checks or at least, to a whitelist of urlsit may be required to work around this problem.

While this works, it requires manual maintenance of the certificate lists, which may not be practical in extreme situations say, new root certs issued every day, although this is unlikely. The other option, akin to the second part of Mike's answer, is disabling revocation checking. Recent versions, 2. Used to enforce or disable certificate revocation checks in cURL when http. Defaults to true if unset. Only necessary to disable this if Git consistently errors and the message is about checking the revocation status of a certificate.

Note that, unlike disabling SSL entirely, this is not inherently less secure than using Mike's answer for specific repositories: if you capture and configure an empty revocation list the usual caseyou have effectively disabled revocation checking.

Disabling revocation checking only becomes a risk in the case of private-key compromise at some point in the chainwhich is rare and difficult. Note, also, that in a corporate MITM setting, revocation checking is being performed for you: no proxy worth using would issue a cert for an invalid or known compromised certificate.
