I've been having the same problem with the launcher myself for the past 4-5 days. Launcher and game client won't connect, but I can tracert (see first link) to the server, and I passed the nettest (see second link). Also tried tracert'ing to the httppatch server, and it showed up as well (can including pic if needed). This has been across 3 computers, 5 different installations, close to 10 different launchers, and 2 OS's. I even installed STO on a computer that's never had it, and still got the same problem. I've also tried port forwarding, and making my PC the DMZ host on my router. Nothing tried has worked. Really annoying when I was playing the previous 2 months fine. :<
I am still having problems, sometimes I can play then the next day all these connection issues. It has to be something they did with the last update. I am goin to cancel if this doesnt get solved soon, its stupid Port 7255 thats hanging up and I DONT KNOW WHY!
