Scrypted HA Add-On - Web UI won't open / "site can't be reached"

I have the Scrypted full version installed as add-on into HA via HACs. When trying to open Web UI, I get the Scrypted login screen, but after entering UN/PW, get error that site can’t be reached and “homeassistant.local refused to connect”. I’ve allowed this site as insecure, but I never get any other certificate pop-ups to accept. Anyone else have this issue / resolution or an issue with the add-on itself?

I believe that is a third party addon. Ask the author. I also found it not to work.
