2 - Restore DNS Settings on iOS

If you experience false-blocking issues on your iOS device, you can restore the original DNS settings in two ways.

Option 1: Temporarily Disable DNS Encryption

Use this method for a quick test to see if the problem is caused by DNS settings:

1. Open the Settings app
2. Go to General > VPN & Device Management
3. In the Restrictions & Proxy section, locate the DNS option
4. Select Automatic to temporarily revert to the system defaults

Option 2: Completely Remove the Profile

To fully remove the DNS encryption configuration:

1. Open the Settings app
2. Go to General > VPN & Device Management
3. Under Configuration Profiles, find public.adguardprivate.com DoT
4. Tap Remove Profile and confirm

If you decide to stop using NullPrivate permanently, it must be because our service has given you a poor experience; we sincerely apologize for the inconvenience.
The public service uses popular blocklists. Due to limited manpower, we cannot know every app’s missed or false blocks.
If you want to customize rules for your personal needs, consider purchasing a private service. It offers dedicated servers at an extremely competitive price to meet all kinds of requirements.

3 - How to Handle False Positives

Some services are considered normal and necessary by one group of users, yet viewed as personal-data collection or advertising by another. For example, a few mini-programs inside WeChat and Alipay that mix services with ads may not work properly, and payment redirects—such as those in parking lots or vending machines—may also fail.

If your blocking rules are too strict, these services can be blocked and stop functioning.

Temporarily Disable Protection

If you need an urgent, temporary fix, you can disable protection for a short time. The change usually takes effect within 10 seconds.

Add the Service to the Allowlist

For services you use regularly, add them to the allowlist to prevent future blocks. The change usually takes effect within 10 seconds.

Temporarily Deactivate Settings

Public-service users can resolve the issue by temporarily deactivating the service. The change usually takes effect within 60 seconds.

6 - Slow Access to Some Websites

Slow Access to Some Video Sites

If you experience slow access to certain websites while using NullPrivate, it may be due to the following reasons:

ECS Support:

NullPrivate’s free tier does not support ECS (Extended Client Subnet). ECS is a DNS protocol extension that allows DNS servers to provide more accurate responses based on the client’s network location. Many CDNs (Content Delivery Networks) use ECS to direct users to the nearest server, thereby improving speed. The free servers are located in Shanghai and Hangzhou.

Impact:

• Slower Speeds: Without ECS, NullPrivate may be unable to direct you to the optimal CDN server, resulting in slower speeds.
• Inaccurate Geolocation: You may be routed to a server far from your actual location, increasing latency.

Solutions:

• Upgrade to Paid Plan: NullPrivate’s paid plans support ECS, which can resolve this issue and improve speed.
• Use Another DNS Server: You can try another DNS server that supports ECS.
