Remote error: tls: unknown certificate

When trying to pull down a new image I am getting the following:

INFO 2019-08-12T11:52:18+00:00 daemon/daemon.go:486 Server error: http: TLS handshake error from 10.255.0.2:52181: remote error: tls: unknown certificate

Not sure what this IP is from?

That’s a local IP, either for the instance or a container. Would you mind expounding a little more on the circumstances you saw the error?

I’m having trouble accessing the instance because the certificate expired and I can’t seem to login. How do I reset the management certificate?

Jeff,
What is displaying that error? I am uncertain how you would encounter that when attempting to visit the web UI. If you are having certificate errors within Chrome, you can type thisisunsafe to bypass them.
