fruity_rudy 16 Posted February 6, 2015 Hey. I solved a lot of issues but this one is new to me: My friend says, when he joins a server, he either: a) can't see the player names from the slots b) when he can see em and he is able to pick a slot, receiving mission file appears and nothing happens and after a while the connection is lost. Could it be a port issue in the router? I'm not quite sure if he got a new one.. Share this post Link to post Share on other sites
_sam 10 Posted February 7, 2015 Hello, Check if he is playing using the development branch. If he does, try switching back to stable version. Happened to some people back then during the alpha, you can try this. Share this post Link to post Share on other sites
fruity_rudy 16 Posted February 7, 2015 no dev branch.. It's simply weird..maybe it's his router and the ports... I have no idea Share this post Link to post Share on other sites

brightness 12 Posted February 9, 2015 Hi this is regarding the MTU; Some routers has a low MTU set sadly since ArmA 3 Devs obv insists this is not their fault cause their verifySignature sends a package set above their MTU the router causes a session lost which makes the verifySignature fail. To sort this out: Your friend has to set his MTU on router to 1490 or 1500 (Recommended 1500) but some routers forbids it (Sadly mine does). Nothing more you can do than making that the devs actually notice this issue and solve it from their end by liking this: http://feedback.arma3.com/view.php?id=22490 Share this post Link to post Share on other sites
fruity_rudy 16 Posted February 9, 2015 ye I figured that already out. But thx for the answer. He can't change it in the router, that's his problem .. pretty sad.. I remember in A2 OA , there was an option for maxpackets or so .. but the entry is gone in A3.. he moved and got a new router and buying a new one only for A3 is not an option atm.. It's a pity when I play and he can't join and cries on TS :/ Share this post Link to post Share on other sites

brightness 12 Posted February 11, 2015 Dwarden, I'm not talking this out of my head, I was told by several people from different communities that MTU has a big effect on this and most of us are unable to change our MTU settings. In fact that this only happen with my router and not my 3G Phone even confirms it more. Share this post Link to post Share on other sites
