[SmartCrawl Pro] No Sitemap Generated – NGINX server

Though your SmartCrawl Pro sais it generated a sitemap.xml file and it’s live, i found that my hosting company (LiquidWeb) on the Managed WordPress Hosting plan (NGINX server) they block public access to the sitemap.xml file for security reasons.
Is there a workaround that you have for us?

Currently as a workaround, I’ve loaded the plugin:
XML Sitemap Generator for WordPress 4.1.0
It contains special code for NGINX servers:

Webserver Configuration
Since you are using Nginx as your web-server, please configure the following rewrite rules in case you get 404 Not Found errors for your sitemap:
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.xml$ "/index.php?xml_sitemap=params=$2" last;
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.xml\.gz$ "/index.php?xml_sitemap=params=$2;zip=true" last;
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.html$ "/index.php?xml_sitemap=params=$2;html=true" last;
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.html.gz$ "/index.php?xml_sitemap=params=$2;html=true;zip=true" last;
' 

I inserted that code as a nginx.conf addition and it worked perfectly.
That’s what gives me hope that you too have a workaround.
Thank you in advance.
