Site setup with localtunnel not working

Not sure if this is a Discourse issue or not, but I’ll ask here.

I set up a site, and tried using localtunnel to put it on the web. It’s configured all correctly, but will not display.

The https:// URL is just the text “404”, and the http:// one is nginx.

Thanks for any help.

Changing the URL, which normally solves Discourse issues for me didn’t help.
I also have a Strict SSL rule if that adds anything.
