Halo 4 gamer tag saying my status is not joinable

It depends were you in a game that was full or a full lobby.

Or your in a private game or lobby

Is your NAT open?

This is my account and I'm 26 I don't have any parental controls set I'm allowed to look and do as I please. This is the only game I have been playing other than halo reach which I haven't played since halo 4 came out. Like I said before my nat is always
in open status but I am unable to join any friends they all say not joinable and on the occasion they say joinable they have a padlock next to the join player button which does nothing when I hit the button to join.

This is me again using my proper gamer tag to again say that I cannot upload to fileshare on Halo 4 as it says my name is not allowed on XBOX live.

Thanks for your time.

I'm having the same problem. When I first log in and start playing, I'm able to join friends and play a few war games. Then I get kicked from a game and from that point on I can't join anybody. It say's they are joinable, but as soon as I click the button,
it says not joinable.

If I back out of Halo 4 and come back in, I am able to join my friends again for a few games before I get kicked again.

Ok, i hope you find the information need, because i live in russia.

But the modem and router both seem to be foriegn, most likely both well known brands.

The modem is: Motorola 136052070

On the modem there is also a writing: SURFboard model:SB5101E. Not sure what that means.

The router is: upvel model ur-315BN
