How to install Portal SSL certificates on Omada Controller software 3.2.0

@KenzyWilliams, you can try this recipe: https://community.tp-link.com/en/business/forum/topic/150083 and add the controller's IP as a Subject Alternate Name (SAN) to the certificate, but I never tested it with the portal page.

Anyway, if you use HTTPS redirect this won't help at all to prevent the browser's warning if users address a foreign domain and get redirected to the portal.

Note that this recipe works only for Omada Software controller, but not for OC200.
