Issue with Plex as subfolder requests going to port 4443

[ZeroTwoCode]

Describe the bug

• NginxProxyManager v2.8.1
• When setting up Plex as a subfolder, it is requesting assets through port 4443 and these aren't being rewritten correctly. Some requests are successful and some aren't. I have migrated from swag and used the same config except for NPM listens on port 4443 whereas swag was 443.

To Reproduce

1. Set up Plex as subfolder
2. Go to https://yourdomainname/plex
3. Check network activity to see failed requests to port 4443

Expected behavior The requests to port 4443 should be rewritten to port 443.

Screenshots Successful request to port 443

Failed request to port 4443

Config

location /plex {
    return 301 $scheme://$host/plex/;
}
if ($http_referer ~* /plex) {
    rewrite ^/web/(.*) /plex/web/$1? redirect;
}

location ^~ /plex/ {
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Scheme $scheme;
    proxy_set_header X-Forwarded-Proto  $scheme;
    proxy_set_header X-Forwarded-For    $remote_addr;
    proxy_pass       http://192.168.1.2:32400;

    rewrite /plex(.*) $1 break;

    proxy_set_header X-Plex-Client-Identifier $http_x_plex_client_identifier;

}

NPM does not listen to any other ports than 80 and 443. Try to add this to the advanced settings to enable 4443 as well:

listen 4443;

But I suggest to change everything to 443 as you can't forward ports with IPv6.
