Expired Certificate and Dropped Passwords?

So myself and my coworker have inherited a system that is running on a bunch of Digital Ocean boxes and is managed by Rancher. All has been well and good while we learn how to use Rancher.

As of 3 days ago, however, we are getting privacy errors saying that the https certificate on the server used for logging into Rancher has expired and NONE of our passwords are working. There’s no option for recovering the password either.

We’re basically at a loss as to where to go from here, just looking for pointers.

If you’re talking about the certificate on Rancher itself, that’s managed by “you” in a proxy server, hardware balancer, ELB, or etc outside of Rancher.

If you’re using AD or other auth to talk to a server that’s serving up an expired cert, then refusing to use it is “correct”, if unhelpful. Update the server.

If for some reason you can’t (e.g. needs a different CA cert chain) or you just want to give up and setup auth again, see http://rancher.com/docs/rancher/v1.6/en/faqs/troubleshooting/#authentication
