Unable to Join

Having an issue playing consecutive matches. After finishing one match i always get an unable to join message. I get it with and without being in a party (only i get booted to main menu) and every game type (arena/warzone/firefight). NAT is open with wired connection and 50mb download. Is anyone else having this issue?

been a month, still no change.

I have a similar issue but instead it says loading information from the halo reach server. I can’t even get into a game so ur lucky.
