I’m trying Rancher Desktop for the first time and ran into this! (Although, I was running a Postgres container.) On the first run, I can successfully connect, but upon restarting the container, I can no longer connect. I can reproduce the failure described in https://github.com/rancher-sandbox/rancher-desktop/issues/1411#issuecomment-1059532691.

Rancher Desktop 1.2.1 Kubernetes disabled Container Runtime: containerd macOS 11.6.5 (Intel)

I can also confirm that it works fine with the dockerd (moby) runtime.

Doesn’t sound like this is resolved, so going to re-open for further investigation.
