Hi, I am facing a problem with Rancher when adding additional registries to a cluster (e.g. via Cluster Management -> Edit Config -> Registries. I just want to add additional registries with their self signed CA’s and leave the default registry as is. Once I add the first registry everything looks fine, and images are pulled correctly from the on-premise registry, but once I add a second registry the first control-plane loses connection with the cluster. RKE2 reports on that failing control-plane the following error:

Failed to test temporary data store connection: failed to dial endpoint <http://127.0.0.1:2399> with maintenance client: context canceled

See screenshot is from the cluster configuration for registries on a downstream cluster Any ideas? Or am I just adding these registries in a incorrect way?
