Sorry for replying on this thread so many months after, but it seems my brother and I are having the same issue. After getting new WiFi we started to have issues playing on the same fire team. This did not pose an issue with the old router. It says unable to join target player when trying to join the fire team. I (ownu122) cannot join (nlrangers21). I have tried all of the trouble shooting steps I have found on this issue. Any reply would be great. Thank you.
