That's an error from Windows. Schannel is the Microsoft security
infrastructure used to implement SSL/TLS, and it's complaining it cannot
reach the server which tells it what certificates have been revoked. That
server isn't run by us; essentially, it's all Microsoft code and
infrastructure.

You'd need to figure out why your system cannot reach the revocation server.
