It's possible that your VPS's IPv6 privacy extensions is activated. When this option is enabled, Windows will generate its own random address. But, when utilizing IPv6, this random address will not function, which might cause random or continuous difficulties.
You can fix this problem by turning off the privacy add-ons. By deactivating the privacy add-ons, you can resolve the issue. To accomplish this, follow the instructions below:
- Copy and paste the following commands:
netsh interface ipv6 set global randomizeidentifiers=disabled store=active
netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent
netsh interface ipv6 set privacy state=disabled store=active
netsh interface ipv6 set privacy state=disabled store=persistent
You should get a “Ok.” message after each command.
After executing these 4 commands, Windows will automatically switch to the right IPv6 address after a few seconds.
