IPV6 & IPV4 When i try send a message it says message failed to send

Do you know if you ISP supports IPv6? Your router could be tunneling your IPv4 connection to an IPv6 which basically means it is sending IPv6 packets through an IPv4 connection to communicate with IPv6 servers. I found out myself the xbox doesn't like
this at all. My ISP doesnt support IPv6. When I would look at my connection on my xbox it would say IPv4 and IPv6. So O went into my router settings and sure enough my router was set to tunnel IPv4 to IPv6. I went through set to IPv4 only and it solved my
problem. This causes a teredo error in your xbox.

ok second step fixed it. thank you so much your a life saver!!

Very welcome, ignore my private message asking which step fixed it, I checked the private message first, glad your issue is resolved!

Hello,

What is the error code you are getting?

Please try some of these steps to try resolve the problem, test it after each step as you might not have to do all of them.

Step 1. Go to settings > System > Storage > (highlight the hard drive, press Y to enter device options) clear system cache. Then shut down your xbox unplug it from the wall (restart router if possible) when the router is fully rebooted, plug the xbox back
in, boot it up and go into network settings and test network connection

If that doesn't work

Step 2. Go to settings > system > storage > hard drive > go through all of your hard drive content and delete any partial incomplete file with a yellow exclamation icon. Once all of them is removed if any please clear system cache again and then just reboot
the console

If this problem.persists there is one last option I would advise before contacting Xbox Customer Support. System update rollback. This will nit affect any gamesaves or DLC. Go to settings > system > storage> highlight the hard drive and press the buttons
in this order > LEFT bumper RIGHT bumper, X, LEFT bumper RIGHT BUMPER, X, thus will prompt you to download the system update again, please ensure no network connection drops while this is done. The console will reboot itself, this should be attempted as a
last resort.

If none of these steps help please contact Xbox Customer Support by visiting
support.xbox.com/contact-us

Additionally it could be an undocumented fault on the servers, but for now we should treat it ad a local problem than server-side

Please keep me posted!

Last addition, step 4. Re-download your gamer tag if all 3 steps fail.

I'm not sure. How can I check if my router is tunneling it through Ipv4?
