Solution

You need to add minikube’s ssh key to your ssh agent

ssh-add C:\Users\user\.minikube\machines\minikube\id_rsa

Issues with ssh-add

Cannot use ssh-add, agent not running

Make sure ssh-agent is running

Get-Service ssh-agent | Set-Service -StartupType Automatic
Start-Service ssh-agent

Permissions for ‘C:\Users\user.minikube\machines\minikube\id_rsa’ are too open.

In case you get “Permissions for ‘C:\Users\user\.minikube\machines\minikube\id_rsa’ are too open.” you might need to copy id_rsa to desktop and change permissions https://superuser.com/a/1296046
