While trying to connect to each other on a fireteam, we were prevented from doing so. My friend ★_SiR_GaLaHaD_★#3722 had unspecified network errors appearing for him when I hosted the fireteam, and when I tried to join his fireteam, it told me it was a "Moderate NAT" issue. We both tried loading into social spaces and other multiplayer content and we saw a few to no players in either case. EDIT, 30 minutes later: The issue fixed itself with no additional input, we have no idea what that was about.
