Due to Microsoft's recent update, some Windows users may be prompted to disable IPV6. Description and solution

Dear 5UF club  Users,

Recently, some users have reported an error message after successful connection:

“Abnormal DNS resolution, IPv6 disabled.”

After investigation, our technical team has confirmed that the issue is caused by a recent Windows update. This update lowered the DNS priority for dial-up interfaces, which affects public DNS services such as Google DNS. This issue has been discussed in several international technical communities.

If you are experiencing the following issues:

• Message saying “Abnormal DNS resolution, IPv6 disabled”

• Inability to access websites like Google

• DNS resolution failures

Please follow the steps below to resolve:

How to Fix:

1. After connecting successfully to the Wuyoufu VPN client, go to:

Start → Search for PowerShell → Right-click and choose “Run as Administrator”

2. Then enter the following command and press Enter:

Set-NetIPInterface 5UFVPN -InterfaceMetric 1 

3.This will restore DNS priority and resolve the issue.
