Official servers are unreachable from my region.
I'm on the west coast US. When attempting to connect to any official server the user gets error 0x00001001
I am able to ping the IP address successfully, but client is unable to connect to the server.
Attempting to connect to a community server results in a successful connection.
I believe that there may be a bad gateway refusing the connection.
EDIT -
Work around:
Using Wndows File Explorer. Navigate to C:\Program Files (x86)\Steam\steamapps\common\DayZ
Right click on the program DayZ_BE and "Run as Administrator" (or just run program)
Game Launches.
Select your server.
Enjoy.
