How to resolve “This network is blocking encrypted DNS traffic” error

4 min read

Most of the time, iPhones are pretty good at connecting to the right networks, making the internet work flawlessly, and protecting your private data.

But what do you do if you connect to a new WiFi network and it gives you a "Privacy Warning"? Tapping on the information icon, you'd generally see one of two explanations:

  • Private WiFi address is disabled for this network
  • This network is blocking encrypted DNS traffic

The second option is much more common and concerning. You might be at risk of exposing your traffic and compromising your privacy. But not to worry, there are quick and simple fixes to this problem. Let's find out how to resolve privacy warning WiFi issues in no time.

What is DNS traffic?

When you get an error message mentioning the "network blocking encrypted DNS traffic," you might wonder what DNS actually means.

DNS stands for domain name system and is akin to a phone book for the internet. A DNS server essentially resolves human-friendly URLs like apple.com to actual IP addresses that computers use.

Since most default DNS servers belong to ISPs (internet service providers), they have an incentive to monitor your traffic and see which URLs you're trying to resolve. But they can only do that if your traffic is not encrypted.

What does "network blocking encrypted DNS traffic" mean?

Privacy-minded companies like Apple are trying to make surfing the web more private and secure for all, implementing features that hide your IP, block third-party trackers, and more.

Since some ISPs profit from selling your DNS traffic to marketing companies, they try to block DNS encryption, which prevents them from snooping on you. That's why iOS displays the network blocking warning message.

How to fix "This network is blocking encrypted DNS traffic"

There are lots of potential fixes to privacy warning WiFi issues, from restarting your devices to updating security measures to setting up a VPN. Let's tackle them one by one.

1. Restart your phone and router

As with many other bugs and errors, restarting your device is a great first step. Just turn off your iPhone and turn it back on again. Do the same for your router, waiting for about 15 to 20 seconds before turning it on.

2. Forget and reconnect to the WiFi network

If the problem is not with your device, it might be with the WiFi network. Instead of simply turning your WiFi off and on, you should actually forget the network and reconnect to it.

Here's how to do it on your iPhone:

  1. Go to Settings ➙ Wi-Fi
  2. Tap the info icon
  3. Forget This Network
  4. Select the network again and enter the credentials to reconnect

Forget This Network

3. Update your phone and router

Keeping the software and firmware on your phone and router up to date can help resolve a lot of random bugs and make them more stable overall.

Just log in to your router settings and find the update firmware option. On your iPhone, you can just go to Settings ➙ General ➙ Software Update.

4. Change your router's admin password

In some cases, changing the admin password on your router can resolve privacy warnings such as DNS encryption being blocked. So try logging in to your router's admin settings and changing the password from there.

5. Use the WPA3 security protocol

While you're logged in to your router's admin panel, you can check whether your WiFi is using an up-to-date security protocol.

Most devices now support the WPA3 security protocol, which you should try to change your settings to. Normally, you can do it in the access point or advanced security section. A WPA2/WPA3 protocol will also work well and still provide support for older devices.

6. Disable network monitoring apps

Some routers have traffic analyzers, which monitor the websites you visit. You might have also installed third-party traffic analyzers in the past. Turning them off might make the privacy warning message disappear.

7. Install a VPN

If none of the tips above managed to resolve privacy warning messages, it might be that your ISP is actively trying to monitor your traffic.

Since your DNS encryption is disabled, you can turn to a VPN (virtual private network) to restore your privacy. Using a VPN means your DNS traffic will be routed through the VPN's servers, so it's important to choose a great VPN you can trust. Like ClearVPN.

ClearVPN is an effortless VPN app available for both Mac and iOS devices. Instead of complex configurations, ClearVPN offers one-click shortcuts for anything you want to do, from safely downloading files to streaming sporting events to changing your server location.

Most importantly, using ClearVPN would protect you from the prying eyes of your ISP and resolve privacy warning messages you might get.
