View Site Not Working (URL Blank on Web Browser)

Hello, I’m new to Local by Flywheel, and I’m getting the exact same problem as the description above (with the same mac OS version & site config) except that trying Safari didn’t work & restarting Chrome (or typing chrome://restart in the browser bar) didn’t work – I still have an empty page. I have a live website that I’d like to work on in Local by Flywheel, and I just imported it.

Interestingly, when I go to the site’s admin (https://mysite.local/wp-login.php) I can log in and it looks fine (I didn’t test extensively, but it looks just like the live site’s). It’s only when I try going to https://mysite.local/ , including via Visit Site from the WP admin dashboard, that I get a blank page.

Some details in case this helps:

In Chrome DevTools, on the network tab:

The request headers on the local site looked quite a bit different:

And yes, I do have Apache selected as my webserver. But that may not have anything to do with anything. - Edit: I noticed in Nginx headers for Apache server? - Support - Local Community that @clay explains the reverse proxy, so I guess that explains that.
