WordPress in Docker container throws error 500 with Post title permalinks

I am trying to host WordPress blog under a subdirectory URL like:

https://example.com/blog

Because I have another application running on https://example.com/ Everything is under a Nginx reverse proxy

To do so, I created the following environment:

Docker Compose.yml

# docker-compose.yml
version: '3'

services:
    wordpress_seo:
        image: wordpress
        restart: always
        ports:
            - 8094:80
        environment:
            WORDPRESS_DB_HOST: db-wordpress_seo
            WORDPRESS_DB_USER: ${MYSQL_WORDPRESS_USER}
            WORDPRESS_DB_PASSWORD: ${MYSQL_WORDPRESS_PASSWORD}
            WORDPRESS_DB_NAME: ${MYSQL_DATABASE}-wordpress
        volumes:
            - ${STORAGE_PATH}/wordpress:/var/www/html
        networks:
            - env-dev

    db-wordpress_seo:
        image: mariadb:10.1.41
        restart: always
        environment:
            MYSQL_DATABASE: ${MYSQL_DATABASE}-wordpress
            MYSQL_USER: ${MYSQL_WORDPRESS_USER}
            MYSQL_PASSWORD: ${MYSQL_WORDPRESS_PASSWORD}
            MYSQL_RANDOM_ROOT_PASSWORD: '1'
        volumes:
            - ${STORAGE_PATH}/wordpress-data:/var/lib/mysql
        networks:
            - env-dev

networks:
    env-dev:
        external:
            name: env-dev

With this config inside my server Nginx config:

    location /blog/ {
        proxy_pass http://127.0.0.1:8094/;
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_read_timeout    90;
        proxy_connect_timeout 90;
        proxy_redirect        off;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Port 443;

       proxy_set_header Proxy "";
    }

Then I modified the wp-config.php by adding this:

define('WP_HOME','https://example.com/blog');
define('WP_SITEURL','https://example.com/blog');

if (strpos($_SERVER['REQUEST_URI'], '/blog/wp-admin/') === false) {
    $_SERVER['REQUEST_URI'] = str_replace("/wp-admin/", "/blog/wp-admin/",  $_SERVER['REQUEST_URI']);
}// If we're behind a proxy server and using HTTPS, we need to alert WordPress of that fact

// see also https://wordpress.org/support/article/administration-over-ssl/#using-a-reverse-proxy
if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false) {
    $_SERVER['HTTPS'] = 'on';
}

Installation went well, and I could access to articles with this kind of permalink:

https://example.com/blog/?p=1

However, I want now to use post title permalinks. So when I do the switch inside WordPress config panel, posts suddenly throw a 500 error, for example if I access this URL:

https://example.com/blog/bonjour-tout-le-monde/

I checked for the .htaccess file in my container which seems to be fine:

# BEGIN WordPress
# Les directives (lignes) entre « BEGIN WordPress » et « END WordPress » sont générées
# dynamiquement, et doivent être modifiées uniquement via les filtres WordPress.
# Toute modification des directives situées entre ces marqueurs sera surchargée.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /freelance/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /freelance/index.php [L]
</IfModule>

# END WordPress

When I check for logs in my WordPress container with huge verbose activated, I get the following (I removed some parts because it's just a repeating pattern):

Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
r->uri = /blog/index.php, referer: https://example.com/blog/wp-admin/edit.php

redirected from r->uri = /blog/index.php, referer: https://example.com/blog/wp-admin/edit.php
redirected from r->uri = /blog/index.php, referer: https://example.com/blog/wp-admin/edit.php
redirected from r->uri = /bonjour-tout-le-monde/, referer: https://example.com/blog/wp-admin/edit.php
Response sent with status 500, referer: https://example.com/blog/wp-admin/edit.php

Do you have any idea where the bug is coming from?

For those wondering what is the solution, you have to edit the .htaccess file of wordpress and override wordpress automatically generated rules.

This is my .htaccess file now :

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>


# BEGIN WordPress
# Les directives (lignes) entre             BEGIN WordPress             et             END WordPress             sont g      n      r      es
# dynamiquement, et doivent       tre modifi      es uniquement via les filtres WordPress.
# Toute modification des directives situ      es entre ces marqueurs sera surcharg      e.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>

# END WordPress
