Solved: Why captive portal won’t connect.

currently on Version 12.3.1 Monterey also tested on Sierra

When connecting to a public wifi that uses captive.portal.com to connect to the portal I got the following message.

”Could not connect”

safari can’t find server

safari can’t open page “https://captive.portal.com” because Safari can’t find the server “captive.portal.com”

Solution 1: Remove all hard coded DNS Servers from (System Preferences—-> Network ——-> Wifi Connection ——> Advanced ——> DNS)

Solution 2: Wipe all cookies and Website data from within the time you got the message.

Solution 3: Disconnect and reconnect to the wifi

Solution 4: Open a safari browser and navigate to the FQDN of the portal.

if it presents success you are now on, if it does not please see solution 1

hope that helps as the last existing thread did not do much for me.
