refused to connect. unable to display web page

[neffen37]

hello after installing FullPageOS I tried to put the url of my HomeAssistant home automation and it gives me an error refused to connect. see photo
I also tried with google.fr and it's the same, I don't know what it could come from

1. moving to a discussion, this is a network issue on your particular network and not a FullPageOS issue. Other people got home assistant working
2. what is the IP of the Pi?
3. is there some kind of client isolation on the network? Can other devices that are connected to the same wifi/ethernet reach it?

ok my network is 192.168.0.1/24 and the pi is 192.168.0.186 i have ssh and vnc acces no problem I don't have a vlan or particular config and my router is opnsense but I have the impression that either there is a problem with the browser (an updated one) or the integrating firewall because with another basic Debian distribution the browser works perfectly well
