Can't connect to HA dasboard


I just change ISP and modem.
I have a Netgear router with all my setup for my network who follow me when I change ISP.
Now I don’t have access to my dashboard with http://my_ip:8123 or my duckdns adress but I also have an home kit integration on my HA and it’s works.
I can turn on and off my light or my switches, my automations works well too.

how can fix this ?
