Issues with NGINX Rewrite Rules

i tried it now several times but it won't work. I have a Server which running Debian 10 with NGINX and Wordpress installed.

Now i need to rewrite some old URLs to the new place.

We must rewrite URLs like this:

example.com/artikel.html?id=##ID##&meldung=###Meldung### to example.com/artikel/$2

server_name example.com www.example.com;
root /var/www/example.com;

index index.html index.htm index.php;
access_log /var/log/nginx/example.com_access.log;
error_log /var/log/nginx/example.com_error.log;
set $skip_cache 0;

# POST requests and URLs with a query string should always go to PHP
if ($request_method = POST) {
set $skip_cache 1;
}

if ($query_string != "") {
set $skip_cache 1;
}
# Don't cache URIs containing the following segments
if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php
|sitemap(_index)?.xml") {
set $skip_cache 1;
}

# Don't use the cache for logged-in users or recent commenters
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass
|wordpress_no_cache|wordpress_logged_in") {
set $skip_cache 1;
}
location /Artikel {
rewrite ^/Artikel.html(.*)$ https://example.com/artikel break;
}

location / {
add_header Front-End-Https on;
add_header Cache-Control "public, must-revalidate";
add_header Strict-Transport-Security "max-age=2592000; includeSubdomains";

proxy_set_header X-Real-IP $remote_addr;

}
