Having Trouble with 'ping ipv6'? Why Can't I Ping an IPv6 Address Successfully?

This might sound dumb, but have you tried restarting your router? I know it’s cliché, but sometimes routers just need a reset to properly handle IPv6. Also, check if your modem supports IPv6—some older ones don’t. If all else fails, try using a VPN that supports IPv6 to see if it’s an issue with your local network.
