Hi everyone! I use Rancher Desktop on my personal laptop and now I'd like to install it on my work computer. This one is connected to a secure network behind a proxy. Both are running Windows. These URLs have been whitelisted, and https://objects.githubusercontent.com/* as well to download K3s. However, the cluster startup gets stuck at step "Starting Kubernetes" and displays the following error after 5 minutes:

Kubernetes was unable to start: Error: tunneling socket could not be established, statusCode=407

I checked the logs, but they don't help much. Any idea what could be causing this?

407 indicates a proxy auth. windows or mac? wsl has a proxy setting and mac is a bit more w limavm

Thanks @wide-mechanic-33041, I agree with you about the 407 error and I'm looking in that direction. But I can't figure out what the problem is 😞 Rancher Desktop's proxy settings seem to be set correctly. When I run a cURL in rancher-desktop wsl, I can reach URLs that are only open to me in the proxy. I am running Windows and WSL is up to date.

well 407 means it has a proxy (possibly through the WSL autoProxy feature). You may be competing with autoProxy as I am not 100% how the auth is being sent via the WSL config pane in RD. You may want to try and disable autoProxy and see if your results change. The 407 is a auth challenge response so its getting the proxy, but not the auth to use the proxy.
