How to fix 'This network is blocking encrypted DNS traffic” on iPhone

"Privacy Warning" appears when iPhone connects to WiFi? Easy to solve!

Normally, iPhones can connect to the network smoothly and protect your privacy data. But sometimes when connecting to a new WiFi network, a "Privacy Warning" will pop up, prompting "This network has disabled private WiFi address" or "This network blocks encrypted DNS traffic". The latter is more common and more worrying because it can cause your network traffic to be exposed, thus endangering your privacy. Don't worry, it's easy and quick to solve this problem.

What is DNS traffic?

The DNS in "Network Blocks Encrypted DNS Traffic" refers to the domain name system, which is the "phone book" of the Internet. DNS servers convert easy-to-understand URLs (such as apple.com) to IP addresses used by the computer. Most default DNS servers belong to Internet Service Providers (ISPs) and they have the motivation to monitor your traffic and see the URLs you are trying to parse. But they can do this only if your traffic is not encrypted.

What does "network block encrypted DNS traffic" mean?

Privacy-oriented companies such as Apple are committed to improving the privacy and security of web browsing, implementing functions such as hiding IP and blocking third-party trackers. Since some ISPs make money by selling your DNS traffic to marketing companies, they will try to block DNS encryption, thus preventing you from being snooped. This is why iOS displays network blocking warning messages.

Note: The ISP can only see the websites you are trying to parse, not the actual traffic between you and those websites (provided that you use HTTPS, which is why HTTPS is so important).

How to resolve the issue of "This network blocks encrypted DNS traffic"?

There are many ways to solve the WiFi privacy warning problem, from restarting the device to updating security measures to setting up a VPN, let's solve it one by one.

1. Restart your phone and router

For many errors, restarting the device is the first step. Close your iPhone and turn it back on. Do the same for the router, wait for about 15 to 20 seconds before opening.

2. Forgot and reconnect to WiFi network

If the problem is not on your device, it may be related to the WiFi network. You should forget about the network and reconnect instead of simply turning off and on WiFi.

How to operate on iPhone is as follows:

1. Go to Settings → “Wi-Fi”
2. Click on the info icon
3. Forgot this network
4. Reselect the network and enter the credentials to reconnect

3. Update your phone and router

Keeping the software and firmware of your phone and router up to date can help resolve many random errors and improve their overall stability. Log in to router settings and find update firmware options. On your iPhone, you can go to Settings → General → Software Update.

4. Change the administrator password of the router

In some cases, changing the router's administrator password can resolve privacy warnings such as blocking of DNS encryption. So, try to log in to the router's administrator settings and change the password.

5. Using WPA3 Security Protocol

After logging into the router's administrator panel, you can check whether your WiFi is using the latest security protocol. Most devices now support the WPA3 security protocol, and you should try changing the settings to this protocol. Typically, you can do this in the access point or in the Advanced Security section. The WPA2/WPA3 protocol also works properly and still supports older devices.

6. Disable the network monitoring application

Some routers have traffic analyzers that monitor the websites you visit. You may have installed third-party traffic analyzers in the past. Turning them off may cause the privacy warning message to disappear.

7. Install VPN

If all the above tips fail to resolve the privacy warning message, it may be that your ISP is actively trying to monitor your traffic. Since your DNS encryption is disabled, you can use a VPN (virtual private network) to restore your privacy. Using a VPN means that your DNS traffic will be routed through the VPN's server, so it's important to choose a trusted VPN, such as ClearVPN.

ClearVPN is a simple and easy-to-use VPN app for Mac and iOS devices. ClearVPN offers one-click shortcuts for doing whatever you want, from safely downloading files to streaming sports events to changing server locations.

Most importantly, using ClearVPN protects you from ISP snooping and addresses privacy warning messages you may receive.
