Rancher desktop error when starting kubernetes

Question

My Rancher desktop was working just fine, until today when I switched container runtime from containerd to dockerd. When I wanted to change it back to containerd, it says:

Error Starting Kubernetes
Error: unable to verify the first certificate

Some recent logfile lines:

    client-key-data: LS0tLS1CRUdJTiBFQyBQUklWQVRFIEtFWS0tLS0tCk1IY0NBUUVFSUV1eXhYdFYvTDZOQmZsZVV0Mnp5ekhNUmlzK2xXRzUxUzBlWklKMmZ5MHJvQW9HQ0NxR1NNNDkKQXdFSG9VUURRZ0FFNGdQODBWNllIVzBMSW13Q3lBT2RWT1FzeGNhcnlsWU8zMm1YUFNvQ2Z2aTBvL29UcklMSApCV2NZdUt3VnVuK1liS3hEb0VackdvbTJ2bFJTWkZUZTZ3PT0KLS0tLS1FTkQgRUMgUFJJVkFURSBLRVktLS0tLQo=

}

Tried reinstalling, factory reset etc. but no luck. I am using 1.24.4 verison.

I just got the same error, did you solved it (: – nforced Nov 06 '22 at 23:04 — nforced, Nov 06 '22 at 23:04
No, sadly no, I stopped using it after that. – susgreg Nov 23 '22 at 21:32 — susgreg, Nov 23 '22 at 21:32

TLDR: Try turning off Docker/Something that is binding to port 6443. Reset Kubernetes in Rancher Desktop, then try again.

Try checking if there is anything else listening on port 6443 which is needed by kubernetes:rancher-desktop.

In my case, lsof -i :6443 gave me...

 ~ lsof -i :6443
