Hi guys, I'm facing an issue with my rancher setup and I have battled a lot and couldn't fix it, I just want to see if this is something obvious before bothering opening a github issue. Scenario: I have rancher:v2.1.7 (single node install) deployed with a custom cluster with a single node (everything on hetzner). What I have done?: After a proper backup I tried to upgrade to the latest version of rancher using the guide. What happened?: Now my cluster is unavailable and logs says it can't connect to the node api. What I tried?: Followed the restore backup and the rollback guides without success. Any help is appreciated.
