Hi all, I encountered a problem that I can not understand. It is a bit like an upgraded version of my previous encounter problems. Before the problem is I can not access many sites in a mobile network (still not resolved). For example, I can access the twitter, telegram, etc, but google now, some games (COC, Ingress), can not connect to the server. However, they work when use WiFi, so I think that is network operators NAT problem. However, when I upgraded ocserv to 0.10.2, it becomes everywhere. I cannot loading Twitter image, cannot open speedtest.net, the games cannot connect server even though I use WiFi/LAN and computer. At first I thought it was the MTU problem, and then I found that even reducing the MTU has no effect, and like YouTube and other large data packets website work properly. So I need help. I totally not find a common characteristics in those website. TCP/UDP work, large/small data packets work, no error on ocserv log and client log, meanwhile some software work as normal. Example: curl -vvvvv "http://www.speedtest.net/" * Trying 72.21.92.82... * Connected to www.speedtest.net (72.21.92.82) port 80 (#0) > GET / HTTP/1.1 > User-Agent: curl/7.41.0 > Host: www.speedtest.net > Accept: */* > [Long time....] * Recv failure: Connection reset by peer * Closing connection 0 curl: (56) Recv failure: Connection reset by peer Thanks MagicFish1990
