Opening port 443

Ok so I have had a terrible time trying to get home assistant working with smartthings. I just don’t want to pay $5.00 a month for Nebu Casa ( I understand why it cost that). So the most resent video I found he knows what he is talking about. But my problem when I go to port 443 can not bee seen. I am using Eero pro routers. I open port 443 and 8123. I sees 8123 as open. Running Hassio VM on a Unraid machine. any advice ? i also tried the way these people recommend everyone is different
