Apache (Homebrew) on macOS Monterey not reachable from network

I've installed Apache using Homebrew on a Mac Studio (M1) running Monterey and it works fine when working locally. But when I'm working on a website from a separate Ubuntu laptop, I often cannot access the website on the Mac; the request is pending. But when I now connect to the mac by SFTP and navigate around, the web request suddenly succeeds as if I had to "wake up" the Mac. Maybe there's a setting to tell macOS that it should wake up on TCP requests on port 80 as it does on SSH requests?
