Certain pages won't load in iframes, but pages load correctly on their own.

[MDKAOD]

Problem description

Certain pages (getting started, settings, maybe playing) won't load in the iframe section below the booksonic blue bar menu.

Steps to reproduce

Log in. Before today, I never clicked the "Dont show me this again" link on the getting started page, so typically that should load. When opening "Home" in a new tab, I was able to click "Don't show me this again" and the "Home" page now shows up correctly, but settings tab still doesn't load. 'Playing' does nothing, but I don't have anything running at the moment.

1. Log in
2. Observe white screen
3. Slap around trying to see what else works or doesn't

Just to add a bit of information, for me this seems to be happening because I have Booksonic running in docker behind a reverse proxy (Traefik) terminating TLS and that is causing Booksonic to generate http links instead of https - thus generating a mixed content error in the browser console:

[blocked] The page at https://booksonic.myexample.domain/index was not allowed to display insecure content from http://booksonic.myexample.domain/home.view.

According to Traefik docs the X-Forwarded-* headers should be getting delivered to the Booksonic container, so the information to generate the correct URLs is there

I'm happy to try to help investigate the issue if maintainers need more info.

EDIT: After checking the airsonic docs I stopped the application, did this change in the config to use forward headers, and after starting the application it now works correctly for me - https://airsonic.github.io/docs/proxy/prerequisites/#forward-headers

@henriquevcosta Thanks, Henrique Costa! You saved me hours of debugging!
This resolved my error on the initial load of Booksonic:
Mixed Content: The page at 'https://mydomain.com/index' was loaded over HTTPS, but requested an insecure frame 'http://mydomain.com/home.view'. This request has been blocked; the content must be served over HTTPS.
