Sometimes when commanding vagrant up, you can receive this error:
==> homestead: Waiting for machine to boot. This may take a few minutes... homestead: SSH address: 127.0.0.1:2222 homestead: SSH username: vagrant homestead: SSH auth method: private key homestead: Warning: Connection reset. Retrying... homestead: Warning: Authentication failure. Retrying... homestead: Warning: Authentication failure. Retrying... homestead: Warning: Authentication failure. Retrying...
You can cancel this by entering CTRL+C on a Mac.

You can temporarily move/backup this file. When doing a vagrant up or vagrant provision –reload, the private key will be regenerated. And it probably would work again.
You can connect directly temporarily with:
ssh vagrant@localhost -p 2222
You can then reinsert the contents of this file:
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA6NF8iallvQVp22WDkTkyrtvp9eWW6A8YVr+kz4TjGYe7gHzIw+niNltGEFHzD8+v1I2YJ6oXevct1YeS0o9HZyN1Q9qgCgzUFtdOKLv6IedplqoPkcmF0aYet2PkEDo3MlTBckFXPITAMzF8dJSIFo9D8HfdOV0IAdx4O7PtixWKn5y2hMNG0zQPyUecp4pzC6kivAIhyfHilFR61RGL+GPXQ2MWZWFYbAGjyiYJnAmCP3NOTd0jMZEnDkbUvxhMmBYSdETk1rRgm+R4LOzFUGaHqHDLKLX+FIPKcF96hrucXzcWyLbIbEgE98OHlnVYCzRdK8jlqm8tehUc9c9WhQ== vagrant insecure public key
