ProxyPass: Mixed Content in Laravel HTTPS

I'm using Laravel 5.8

Currently I have this site: sample name

https://www.myssldomain.com/ewallet

and

I have this site: sample name

http://my-aws-public-ip/login

Using Proxy Pass included in my myssldomain.com when the users triggers/search for this link : https://www.myssldomain.com/ewallet/login

the browser will load the content of this site http://my-aws-public-ip/login

The proxy pass works fine but the problem is the styles and javascript is not loaded and the browser says Mixed Content because the my-aws-public-ip site is loaded as HTTP not HTTPS

Currently

I changed my config/app.php as

'url' => env('APP_URL', 'https://www.myssldomain.com/ewallet/'),

and

my

.env file I changed the APP_URL to this https://www.myssldomain.com/ewallet/

What I tried

Also

I followed this steps but seems not working too.

Also I tried to change the following just to solve the problem

APP_ENV=production

APP_DEBUG=false

APP_URL=https://www.myssldomain.com/ewallet/

and add this code at the beginning of web.php

if (App::environment('production')) {URL::forceScheme('https');}

But still not working on my side.Is there anything I need to setup just to make sure this will work?

Expected

Using proxy pass from myssldomain.com
