Livewire image previews not displaying on demo site

Temporary images display locally, but not on the demo site.

The images still upload, but the temporary URL's return a 404 error for each image uploaded, and attempting to load the signed URL in a different tab results in a 401.

I'm unsure if my issue is livewire, an error I created, or even possibly this - https://github.com/livewire/livewire/issues/1216 ?

Laravel 8 / Livewire 2 / Forge / DigitalOcean. The demo site is on a sub-domain, and not within a sub-folder. I've updated the upload sizes, the TrustedProxies, and the nginx config updates mentioned in the repo issue, but still have the same issue. I'd prefer not to comment out the abort_unless() line and lose CSRF protection - maybe temporarily for poo-poo's and haha's if requested.

Any and all help appreciated.
