SugarCRM 10.0.3 Nginx Support?

I have followed the KB article for installing Enterprise; https://support.sugarcrm.com/Documentation/Sugar_Versions/10.0/Ent/Installation_and_Upgrade_Guide/#Installing_an_On-Site_Instance

I got through the installation fine, but when attempting to load a page all I get is the Loading... box.

Ubuntu 20.04

Mysql 5.7

PHP 7.3

Nginx 1.18
