Troubleshooting

Captive portal not showing on iPhone

An iPhone opens the login window only when its own check, a request to captive.apple.com, gets the wrong answer. When the window does not appear, either that check is getting through, or the redirect is going somewhere the phone cannot load.

Why is the WiFi login page not showing on my iPhone?

Usually one of five things: the iPhone already has a valid session, Auto-Login is off for that network, the walled garden lets the connectivity check through, the portal domain is missing from the walled garden, or the guest cancelled the window earlier. Forget the network, rejoin with mobile data off, and work through the checks below in order.

Causes, in the order to check them

1. The phone is already authorizedOmada and UniFi

Cause

The controller still has a session for this iPhone from an earlier visit, so the check succeeds and there is nothing to show. This is the system working.

Check

Open Safari and load any plain http:// address. If the real site loads, the phone is online.

Fix

Nothing to fix for guests. For testing, use a phone that has never joined, or wait until the session length set for the location has passed.

2. Auto-Login is switched off for this networkPhone

Cause

iOS lets a user turn off Auto-Login per network, and then the login window does not open by itself.

Check

Settings, WiFi, tap the info button next to the guest network, and look at Auto-Login.

Fix

Turn Auto-Login on, or open Safari and load any http:// address to trigger the redirect manually.

3. The walled garden lets the iPhone’s check throughOmada and UniFi

Cause

If captive.apple.com or a broad wildcard is on the pre-authentication list, the iPhone gets the answer it expects and decides it is online.

Check

Read Pre-Authentication Access (Omada) or Pre-Authorization Access (UniFi). It should contain only www.voqadowifi.com and voqadowifi.com.

Fix

Remove everything else. The walled garden page explains why the list is so short.

4. The portal domain is missing from the walled gardenOmada and UniFi

Cause

The iPhone is redirected correctly but cannot load the page, so the window opens blank or closes, and many guests describe that as “it never showed up”.

Check

Watch closely after joining: a white window that spins, or flashes and closes, points here.

Fix

Add www.voqadowifi.com and voqadowifi.com to the list on the portal bound to this SSID, save, and rejoin.

5. The guest pressed CancelPhone

Cause

If the login window is dismissed, the iPhone stays joined to the network with no internet and no window. Guests read this as the WiFi being broken.

Check

The WiFi icon shows connected, apps say there is no connection, and no window appears.

Fix

Forget the network and rejoin. A small sign near the WiFi name that says “If the login does not appear, forget the network and join again” saves staff a lot of explaining.

Questions

Does Private Wi-Fi Address stop the portal from showing?

No. A private address changes which MAC the controller sees, which affects whether the guest is recognised next time, but the login window still opens.

Why does it work on Android but not on the iPhone?

They run different checks against different addresses. An allow list entry or a stale session can affect one platform and not the other, so always test both.

Should I tell guests to open Safari?

As a fallback, yes. Loading any plain http address in Safari triggers the same redirect the login window would have shown.
