I'm using an iPhone 15 on iOS 26.5. My Wi‑Fi works normally on every other device, and web browsers load without a problem on the iPhone, but apps such as YouTube never connect when I'm on Wi‑Fi. I've already tried changing DNS settings and removing VPN configurations. I don't use an ad blocker or proxy. What else should I check?

If only certain apps are affected, check Settings > Screen Time > Content & Privacy Restrictions and make sure those apps aren’t restricted. It’s also worth setting Date & Time to automatic, restarting the phone and router, and checking whether the router has filtering, parental controls or IPv6 issues that could block app services while leaving regular websites accessible.
First check whether those apps work over cellular data. If they do, go to Settings > Wi‑Fi, tap the info button beside your network, and turn off Limit IP Address Tracking temporarily. Also check Settings > Cellular to make sure the affected apps are allowed to use mobile data, then update or reinstall one of the apps as a test.

Browsers work over this Wi‑Fi, but apps like YouTube still fail to load. I’ll test the same apps over cellular to narrow down whether it’s definitely the network.
