The message that the network is blocking encrypted DNS traffic is an issue that has affected some iPhone users since Apple started supporting encrypted DNS in iOS 14. If you get this message, it is likely you are trying to connect to a network via a router that doesn´t support encrypted DNS rather than your ISP is blocking IP address look-ups for encrypted sites. Depending on your router and ISP there are several fixes for this issue, and we recommend you contact your ISP for device-specific help.
