Postup řešení

  1. 1 Open Network Connections: Press Windows key + R, type 'ncpa.cpl', and press Enter. Look for any tunnel adapters (e.g., 'Teredo Tunneling Pseudo-Interface' or 'Microsoft ISATAP Adapter').
  2. 2 Right-click the tunnel adapter and select 'Properties'. Ensure that IPv6 is enabled and that the adapter is not disabled. If it is disabled, enable it.
  3. 3 If the tunnel adapter is using a specific IPv6 address, verify that it is valid. You can check the address by running 'ipconfig /all' in Command Prompt. Look for the tunnel adapter's IPv6 address.
  4. 4 In Failover Cluster Manager, check the network properties for the tunnel network. Right-click the network and select 'Properties'. Ensure that the IPv6 address and prefix are correct.
  5. 5 If the tunnel network is not needed, you can disable it. In Network Connections, right-click the tunnel adapter and select 'Disable'. Then, in Failover Cluster Manager, remove the network if it is no longer used.
