ServiceUnavailableHttpException on front end, and 404 on admin 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:


&gt; 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.
It turns out it was because I had Apache running and on port 80. I saw something about this somewhere in the guides I followed, but forgot to come back and stop Apache. Oops.
