We have cleared cache on all consoles. Rebuilt database. Uninstalled and reinstalled the game. We have changed modems and routers. We have tried to connect to two separate routers connected to the same modem. We have upnp enabled. We can intermittently join two of our PS4 systems but never the third or fourth. It all started with the rise of iron update. Gamer tags are ACGREY, WDHINTON, tacoguy1960, ladybugz2004, Caboose Llamas. We have hundreds of dollars invested in this game. Getting the error unable to join target players. How about refunding back everything that I have spent on this damn game? I am beyond frustrated at this point! With the amount of discussions on your page obviously there is something going on. Why not just fix it?
