What port number do i have to forward . I already use the Domoticz app outside my Home. I Made a Flore plan, but i don’t know how to set domoticz to https and how do i check if this works ?

Can someone please help me to get controlicz to work with my echo dot 2 .
I made an account on controlicz site and linked it to my echo dot but it does not see my domoticz (raspberry pi).
What am i doing wrong.
