CSRF Token error using Nginx Proxy Manager

Hi, guys
I'm very new to NPM (Nginx Proxy Manager) yesterday I setup NPM with Docker and hosted my Laravel apps,
At first I was getting Mixed Content error (The page was loaded over HTTPS but requested assets over HTTP)
I managed to fix that by following this tutorial (https://geekscircuit.com/how-to-add/)

But now I'm getting many errors like Laravel's CSRF token mismatch, Meilisearch's API Authorization header missing.

I think it has something to do with some headers or something.
But I really don't know how to configure it properly.

My docker-compose.yml

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    container_name: "Nginx-Proxy-Manager-GUI"
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    environment:
      X_FRAME_OPTIONS: "sameorigin"
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
      -  ./_hsts.conf:/app/templates/_hsts.conf:ro # I've just added this from this article (https://geekscircuit.com/how-to-add/)

Many thanks in advance :)

Start with the provided docker-compose.yml and the Nginx Proxy Manager proxy configuration, then reproduce the Laravel CSRF mismatch and missing Meilisearch authorization header through HTTPS. Compare the headers and scheme reaching the applications with those sent by the client; done means the hosted applications work without mixed-content, CSRF, or authorization-header errors.
