If that doesn’t work, try the tips below as well.
1: Turn off and on Wi-Fi
Sometimes simply turning off wi-fi, waiting a few seconds, then turning it back on again is enough to trigger the captive portal page to show up again.
After you turn the wifi off and on on your device or computer, try re-joining the network, then wait a moment for the captive portal page to reappear.
2: Reboot the computer or device
If you turned off wi-fi and back on again, and attempted to rejoin the network to no success, try restarting your computer or device.
You can do this by simply turning your iPhone or iPad off and back on again, or restart your Mac (or Windows PC).
3: Clear DNS Cache
Open the Terminal application and enter the following command, then hit return:
sudo killall -HUP mDNSResponder
This will flush the DNS cache on the Mac.
Wait a moment, then try to join the wi-fi network again, and the captive portal page should show up.
4: Mac users: Did the captive portal page open but get lost?
If you’re on a Mac and have a bunch of open windows and apps, the captive portal login page may have opened but become lost in the sea of open windows.
Turning to Mission Control to see all currently open windows on a Mac by swiping up on the trackpad with three or four fingers. This shows every window currently open on the Mac as a thumbnail, where you may be able to find the captive portal login page on the display.
