Well, if so, you do not need to worry, as we have gathered some potential fixes to resolve this issue. So, if you want to get rid of this error message, make sure to perform the fixes we have mentioned below.

What is DNS traffic?

DNS is a common acronym you might not seem to understand until you receive an error message about “This network blocking encrypted DNS traffic.” It is like a phone book for the internet, meaning a domain name system. In essence, DNS servers resolve humans’ friendly URLs such as apple.com to computer IP addresses.

Due to the fact that most default DNS servers are owned by ISPs (internet service providers), they are able to monitor your traffic and see what URLs you are trying to resolve. It’s only possible if your traffic isn’t encrypted.

Why is my WiFi blocking DNS traffic?

There are a few reasons why your WiFi could be blocking DNS traffic. There’s a possibility that your router is set up to block certain services or websites by blocking their DNS requests. If this setting is enabled on your router, DNS requests won’t be routed to those sites. 

In addition, the faulty configuration might prevent your router from sending outgoing DNS requests. There could be a problem with DNS server settings or a misconfigured firewall or security settings that are responsible for this.

Additionally, your Internet service provider may be blocking DNS requests for maintenance or policy reasons. The first step to finding out why your WiFi network is blocking DNS traffic is to check the settings on your router. You can also check your DNS settings to ensure an accurate DNS server setting.

If none of these options solves your problem, contact your ISP to learn if DNS traffic is blocked. In that case, they should be able to provide you with more details on what is causing the DNS traffic to be blocked and how it can be resolved.

Fix 4: Install a VPN

If none of the tips above worked for you, your ISP might actively monitor your traffic if you are receiving privacy warnings. However, if you wish to restore your privacy, you should use a VPN (Virtual Private Network) because your DNS encryption is disabled. Choosing a VPN you can trust is important since your DNS traffic will be routed through the VPN’s servers.

Fix 5: Use the WPA3 Security Protocol

You can check the latest WiFi security protocol while logging into the router’s admin panel.

You should change your settings to WPA3 security protocol since most devices now support it. It’s usually in the advanced security section of the access point. Additionally, WPA2/WPA3 protocols will also work well for older devices while still providing security.

It’s not uncommon for iOS devices to keep displaying the “This network blocking encrypted DNS traffic.” error message if you’re using a traffic management program to analyze network traffic.

It is common for ISPs to track and store user data online in order to deliver targeted advertisements to third parties. Your ISP won’t be able to see your browsing history if you use a VPN.
