Describe the bug

After updating NPM ( docker compose pull && docker compose up -d) everything was OK until i edited a host.

After that the host started failing. After some debug i found a entry in /var/log/nginx/error.log stating

"map not allowed here"

I managed to find the map entry in the middle of the conf and it's this:

  map $scheme $hsts_header {
    https   "max-age=63072000; preload";
}

This is suffixed on each of my custom locations for that host.

I edited the _hsts_map.conf to comment them and the error was solved, but this won't survive a docker restart.

Research direction

Start with the generated _hsts_map.conf and the Nginx error in /var/log/nginx/error.log; reproduce the failure using docker compose pull && docker compose up -d, then edit and save a host with a custom location. Trace why the map block is appended there, and consider the issue done when the generated configuration reloads successfully without manual edits after a restart.
