Easyform XML Model editor behind nginx fails (in some cases)

Just leaving this here in case anyone else encounters this issue:

I'm building a rather complex easyform with many conditionals. While updating the form that I developed on my local instance to the production server, I noticed that it would not take the updated XML that worked for me locally.

nginx is running in a docker container and logs the request as
10.0.0.245 - - [20/Mar/2025:15:15:26 +0000] "-" 000 0 "-" "-"
Plone never receives it. The nginx config is as vanilla as it gets:

server {

    listen 443 ssl http2;
    ssl_certificate     /etc/ssl/private/mein.pnz.de-chain.pem;
    ssl_certificate_key /etc/ssl/private/mein.pnz.de-key.pem;

    server_name mein.pnz.de;
    access_log /var/log/nginx/plone6.pnz.de.access.log;
    error_log /var/log/nginx/plone6.pnz.de.error.log;

    proxy_http_version 1.1;
    proxy_read_timeout 300;
    proxy_connect_timeout 300;
    proxy_send_timeout 300;
        
    # https://docs.nginx.com/nginx/admin-guide/web-server/compression/
    # text/html is always compressed by HttpGzipModule
    gzip on;
    gzip_types      text/css
                    text/csv
                    text/plain
                    application/javascript
                    application/json
                    application/xml;
                    
    gzip_proxied    no-cache no-store private expired auth;
    gzip_min_length 1000;
    
    location / {
          proxy_set_header X-Real-IP $remote_addr;
          proxy_pass http://plone-backend/VirtualHostBase/https/mein.pnz.de:443/Plone/VirtualHostRoot/;
          client_max_body_size 25M;
    }
}

Have not finished my triage of this error, but know that "simple" forms can be submitted just fine. I validated my XML using Geany's Prettyprint XML plugin, VSCode, and running it by ChatGPT.

Will add more info as I continue debugging and hopefully post a followup in case I find a solution.
