Hi, Thank you for your post. Please ping the local computer and your router with IPv6 address to see the results. If it is successful, we can conclude that the local settings are proper. The failed ping action may be due to different possible factors, such as: the remote server is configured not to respond ping, not all of the network connections between your router and the target support IPv6, and so on. Meanwhile, I will share the following information with you.
