Add por 443 to a container not work

Hi to everyone, i need some help.

I install nextcloud by app sotre and all work fine, I change the config of the Network

I see only :80 in the main config

I need to enter by https (443) but not work

I add this to try but doesn´t work

I notice that in the piHole configuration, i can see the 2 redirects (udp and tcp)

I don´t know why , it´s a simple "external" IP. 

I can´t make the same here. 

Thank!!!
