Solved: Wifi login page not shown

I went to a hotel, and found that when I connect to the wifi, it will soon not connect, and when I try to disconnect the network and connect again, the login page won’t show.

I tried a lot of methods: forget the network and add it again, disable the network and enable it again, and even restart the computer, the login page just doesn’t show.

I searched again from the internet, and find the solution from this page: 10 Fixes for Wi-Fi Login Page Not Showing Up on Mac and Windows, my solution is like below, open the terminal and run the following command:

sudo killall -HUP mDNSResponder

After running the command above and reconnecting the wifi, the login page appeared again, and after I logged in, the connection didn’t lose again.
