JSXC(Java Script XMPP Clinet) for SOGo & Roundcube at CentOS 8

We have installed iRedAdmin console with Roundcube & SOGo mail clients - latest versions. We need to add the chat clients on them (JSXC). Until now , we have tried to make the procedure with Openfire XMPP Server. The Server is already configured with NGINX (and NOT HTTPD service). The problem is that we have never figured out how to make the http_bind for the XMPP openfire server. The Server is running localhost and we will provide you remote access on this machine for the implementation.
