That solution didn't work for me either. I have had this issue since 1.7.2.4 and managed to get into 1 out 10 servers. Now, with 1.7.2.5, I can't connect to anything. Very frustrating. Sixlauncher and dayzcommander give the same result. The thing that has me worried is this: One of the new additions since 1.7.2.4. If I'm constantly logging in and out of servers in an attempt to get into a game, will they see this as a hacking attempt?
