We recently found that our Rancher UI was down. Said there was a proxy/firewall issue but no 504etc. and the subdomain is fine. That is not the case (just the browser).
The first hunch was possibly the Let’s Encrypt cert expired and that was the cause. Don’t think that is it either.
The docker container is there, and when we go in after 10 or so seconds we get booted out. Looks like the etcd is restarting constanly on a boot loop or something. Plenty of resources.
We tried to power down, all the compenent droplets, but that didn’t do any good either.
Being unable to connect remote and use the CLI, any ideas what the cause or solutions we should try would be to;
a) determine what happened and why
Thanks, would love any guidance.
