How to Fix DNS Errors on iPhone (iOS)

Resolve DNS server not responding and website-not-loading errors.

Last verified: February 21, 2026

DNS errors on iPhone commonly present as Safari or apps refusing to load certain sites while the device reports it is connected to Wi-Fi. iOS respects per-network DNS settings configured in Settings > Wi-Fi > tap the i icon > Configure DNS, where switching from Automatic to Manual allows you to specify reliable resolvers like 8.8.8.8. iOS 14 and later also supports encrypted DNS profiles (DoH/DoT) which can be installed as configuration profiles — these provide both faster resolution and privacy benefits, though they also require ensuring the profile source is trusted.

Quick Steps

Follow in order for the fastest result.

  1. 1Forget and rejoin your Wi-Fi network to obtain fresh DNS assignments from the router.
  2. 2Set a reliable public DNS manually: Primary 8.8.8.8, Secondary 8.8.4.4, found in your network adapter or Wi-Fi settings.
  3. 3Restart the browser and test loading sites that previously failed.
