OOPS Sorry ment to post it as an answer in another thread, not use to this forum. So after researching for a while I might have found a "fix" to my issue Port forwarding is kind of restricted on 4g connection. I had to use a VPN to bypass this issue. Everything seems to work fine by now, could see other players, could advance in quests. The only steps I didn't check yet are teaming and pvping. P.S.: You might want to put this fix somewhere as a temporary solution ( we shouldn't have to use a vpn to play a game, so I'm still waiting for a real fix )
