Original GitHub issue: https://github.com/koel/koel/issues/725

I've installed Keol today and so far it works quite well in the local network.
I run all my VMs behind a reverse proxy which serves the domain with SSL.
With Koel however I'm not able to get it working. I get mixed content errors:

Blocked loading mixed active content “http://koel.2li.ch/public/css/app.dfccaba1e91708e1e522.css” koel.2li.ch

I've tried quite a few things to get it working but nothing really worked.
The most promising solution was this one here:
https://stackoverflow.com/questions/29912997/laravel-routes-behind-reverse-proxy
Which I put into routes/web.php however then I get the following error:

 (1/1) BadMethodCallException

Method forceSchema does not exist.

I know there have been other similar errors but none of them seem to have been resolved completely and I think it would be good if there's a place where a setup like this is at least somewhat documented.

I tried to setup the TrustedProxy package for Laravel but didn't succed with that either. Unfortunately I can't run it without SSL because I have setup transport security on the main domain.

Same issue here while using it behind a Nginx reverse proxy. However, I run my web services behind Docker containers, which is essentially the same here.

I tried a lot and then this worked for me (koel 3.7.2):

In koel root, run composer require shin1x1/laravel-force-https-url-scheme
In app/Http/Kernel.php add the following line as line 31:
'Shin1x1\ForceHttpsUrlScheme\ForceHttpsUrlScheme',

The code will look like this:

protected $middleware = [
        CheckForMaintenanceMode::class,
        UseDifferentConfigIfE2E::class,
        ValidatePostSize::class,
        TrimStrings::class,
        ConvertEmptyStringsToNull::class,
        'Shin1x1\ForceHttpsUrlScheme\ForceHttpsUrlScheme', // NEW LINE
    ];

This solution relies on this package.

@Redsandro commented on GitHub (Feb 18, 2019):

The solution by @baumschubser works for me. Except the require command hangs.

I had to:

composer require shin1x1/laravel-force-https-url-scheme
^C (Ctrl + C)
composer update
composer install
Add 'Shin1x1\ForceHttpsUrlScheme\ForceHttpsUrlScheme' to Kernel.php

The problem is, everything is undone when watchtower downloads a new docker container.

It would be much appreciated if @phanan could implement functionality that allows running the koel container (e.g. above fix configurable) behind a proxy container, as this is increasingly common.

Something for people who are getting bored from doing this every time again:

docker exec -t --user 65534:100 koel composer require shin1x1/laravel-force-https-url-scheme -d /opt/koel
docker exec -t --user 65534:100 koel composer update -d /opt/koel
docker exec -t --user 65534:100 koel composer install -d /opt/koel
docker exec -t --user 65534:100 koel sed -i "/ConvertEmptyStringsToNull::class,/a 'Shin1x1\\ForceHttpsUrlScheme\\ForceHttpsUrlScheme'," /opt/koel/app/Http/Kernel.php

Note: Replace --user with your own values.

I am looking into packaging koel for Cloudron and hit the same issue. As far as I understand the env file, shouldn't those URLs be generated from the APP_URL variable?

I agree with @nebulade, URLs should be generated from APP_URL, however, changing APP_URL seems to have no effect.

I'm closing this as the initial issue has seemed to be resolved. If APP_URL still is not behaving as expected please open a new issue to address that.
