Captive portal login page not loading, explained and fixed

You join a hotel, airport, or cafe Wi-Fi network, but the sign-in page, known as a captive portal, never appears, so nothing loads. The network is holding your traffic until you sign in, but the redirect to the login page is being blocked somewhere on the way.

The fix, in order

  1. Open a plain website address. In the browser, try opening a non-secure address such as neverssl.com or example.com. Captive portals work by redirecting plain web traffic, so a secure site will not trigger the redirect.
  2. Turn off any VPN. A VPN hides your traffic from the portal, so the redirect never happens. Disconnect the VPN, sign in to the Wi-Fi, then reconnect the VPN afterwards.
  3. Forget the network and reconnect. Remove the saved network and join it again, which forces the portal redirect to run from scratch.
  4. Flush the DNS cache. On Windows, open Command Prompt as administrator and run ipconfig /flushdns. A cached DNS answer can stop the portal page from loading. You can test whether the portal address resolves with the DNS lookup tool.
  5. Try another browser or a private window. A browser extension, ad blocker, or cached page can block the redirect, so test in a private window with extensions off.
  6. Check the DNS settings. If the device uses a custom DNS server, switch it back to automatic. Custom DNS can prevent the portal redirect from working.
Only sign in to a captive portal through the browser page the network itself shows. Never enter a password for another account on a Wi-Fi login page, and avoid banking or sensitive logins on public Wi-Fi without a VPN.

If it still happens

If the portal page loads on other devices but not this one, the problem is on this device, so try the private window and DNS steps above. If no device gets the portal page, the venue's network is at fault, so ask the staff to restart their access point or give you the direct login address.

Common questions

What is a captive portal? It is the sign-in page shown by public Wi-Fi networks in hotels, airports, and cafes. The network blocks internet access until you accept terms or enter a code on that page.

Why does the portal page work on my phone but not my laptop? The phone and laptop handle the redirect differently, and the laptop may have a VPN, a custom DNS setting, or a cached page blocking it. Turning off the VPN and opening a plain website address usually fixes it.
