What is a Private DNS Server?
A Private DNS server is used to encrypt DNS queries, protecting your online privacy. Unlike traditional public DNS servers, a Private DNS server transmits data over secure protocols like DNS-over-TLS (DoT) or DNS-over-HTTPS (DoH), ensuring that your DNS requests are not intercepted or tampered with by third parties. By routing your DNS requests securely, Private DNS increases privacy and security, preventing surveillance and DNS poisoning attacks.
Common Causes of “Private DNS Server Cannot Be Accessed” Error
This error may arise from several issues that prevent your device from connecting to the Private DNS server. The common causes include:
-
Incorrect DNS Configuration: If the Private DNS provider’s hostname is entered incorrectly, your device will not be able to reach the DNS server.
-
Weak or Unstable Network Connection: Poor Wi-Fi or mobile data connections can disrupt DNS server access.
-
Security Software Interference: Firewall settings, VPNs, or proxy software can block DNS traffic, causing the error.
-
ISP Restrictions: Some Internet Service Providers may block DNS traffic or restrict access to specific DNS servers.
By understanding the potential causes, you can target the right solution to fix the issue.
How to Fix the “Private DNS Server Cannot Be Accessed” Error
Follow these troubleshooting steps to resolve the error:
-
Check the Private DNS Hostname:
Ensure that the correct DNS provider’s hostname is entered in your device’s settings. Common hostnames includedns.googlefor Google DNS and1dot1dot1dot1.cloudflare-dns.comfor Cloudflare DNS. If the hostname is incorrect, your device will fail to connect to the Private DNS server. -
Restart Your Router:
Sometimes, the issue may stem from your home network. Power cycle your router by turning it off, waiting for 30 seconds, and turning it back on. This can clear any network issues and allow your device to reconnect properly. -
Switch to a Different Network:
If you're using a weak Wi-Fi connection or unstable mobile data, try connecting to another Wi-Fi network or switch to mobile data. A stronger network connection might help your device connect to the Private DNS server successfully. -
Disable Security Software:
Firewalls, VPNs, or proxy services on your device or router may block DNS traffic. Temporarily disable any security software, including VPNs, and check if the error is resolved. You can later configure your VPN settings to ensure they don’t interfere with DNS connections. -
Update Your Device’s Operating System:
Ensure that your device is running the latest software update, as outdated versions may cause compatibility issues with DNS settings. Check for system updates and install them if available. -
Clear DNS Cache:
DNS cache stores previous DNS queries to speed up browsing. If the cache contains outdated or corrupted DNS records, it can lead to errors. Clear the DNS cache on your device to ensure fresh DNS queries are used. -
Try a Different DNS Provider:
If the issue persists, consider switching to a different DNS provider. Google DNS and Cloudflare DNS are excellent alternatives for Private DNS. To use them, simply enter their hostnames in your device’s Private DNS settings.

Troubleshooting Advanced Issues about Private DNS
If you’ve followed all the steps above and the error persists, consider these additional troubleshooting methods:
-
Check Router Settings: If your router is configured with its own DNS settings, make sure that the DNS settings align with your device’s Private DNS settings. Misconfigurations in your router can cause devices to be unable to access the DNS server.
-
Consult Your ISP: In rare cases, your ISP may be blocking access to certain DNS providers or the DNS-over-TLS/DoH protocols. Contact your ISP to ensure they are not restricting access to DNS servers.
-
Test with Another Device: To verify whether the issue is with your device or network, try connecting to the same network with another device. If the second device can access the DNS server, the issue may lie with your device’s settings.
