Trying to get started with Craft CMS 3 for the first time, and it's running locally via Valet. from the front end, I get:
> HTTP 503 – Service Unavailable – craft\web\ServiceUnavailableHttpException
And on the admin side, I'm getting a 404. I've looked at similar questions, but none of the answers are helping me. I've set this up twice following this article on running Craft with Valet, and gotten the same result both times.
