Until recently , my friends and I played Arma regularly , with me as the host and them connecting. In the last three weeks however , they cannot see any game I am hosting, and vice versa. We have tried using the filter , and using the Ip address but nothing seems to work. We have tried using the servers in steam settings also , but nothing. I have sent direct game invites via the steam friends list , and although I am showing up as playing arma 3 in-game the server shows not responding. I have posted the question on the forums , and have searched for similar posts to try and resolve this , but still nothing. We have set up port forwarding on all routers also. This is driving all of us loopy , please can someone help us reconnect and start enjoying the game again. many thanks
