Problem with Rancher when scaling up about docker-machine-driver-hetzner

[michafn]

Addition: another issue we came across before it didn't work anymore at all: when creating a new node, the internal IP was used as external IP, which leads to a situation where the external IP and internal IP are the same: the internal IP. I assume this can be sort of a mapping issue? Anyone else got this?

Update: I tried to spin up a new cluster with the hetzner node driver, which actually works as expected. So it somehow seems that the issue lies in the cluster itself. So the core question would be then: why does it work to create ssh keys and machines for cluster B whereas it doesn't work for cluster A. this seems quite irrational since the driver configuration is exactly the same for both. how can that be? Even when using the same node template, there can't be much differences or am i missing an important part here somewhere?

Do you recall what version you had before updating to 5.0.2?

I've experienced the same issue when upgrading 3.13.0 => 5.0.2. Setting the version back to 3.13.0 didn't help. Had to restore my rancher instance from a backup and only then did version by version update (tested scaling up/down after each) and managed to make it work up until 5.0.2 for "old cluster".
