PfSense acme certificates timeout fix

By default we might have following error with Acme plugin of pfSense.

xxxx/xx/xx xx:xx:xx [error] xxxxx#xxxxxx: *xxxx upstream timed out (60: Operation timed out) while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: , request: "POST /acme/acme_certificates.php HTTP/2.0", upstream: "fastcgi://unix:/var/run/php-fpm.socket", 

Add the following properties to <webgui> in /conf/config.xml file. If you add 300000 ms then it means 5 minutes.

<webgui>
    ...
    <connection_timeout>300000</connection_timeout>
    <server_timeout>300000</server_timeout>
</webgui>

For old versions:

In pfsense, the nginx conf file is at /usr/local/etc/nginx/nginx.conf

 keepalive_timeout  300;
  
    location / {
      root   /usr/local/www/nginx;
      index  index.html index.htm;
      proxy_read_timeout 3600;
    }
