Your image doesn’t include the URL of your portal, and I can understand why you might not want to give out a public address. However, be aware that if you are accessing the portal via an address like “https://localhost/litu/portal”, then it won’t be accessible to anyone else anyway. A working portal access would be something more like “https://someclinic.com/openemr/portal” or maybe just “https://someclinic.com/portal” depending on the web server setup. What is the URL specified in the ServerName directive of the virtual host configuration file for your OpenEMR installation?
