The launcher is fundamentally broken due to all the fake servers. Many real servers are not showing up due to what I suspect is some sort inability of the launcher to handle all the fakes. There are several ways to verify this.

1. My server does not show up 99/100 times. In this process I have verified that it is valid on the steam master list by querying the steam masters directly (will provide more on this below.
2. You can go to BattleMetrics, sort by top servers, attempt to search for them in the launcher. 9/10 will not show up
3. Look at many the servers on the launcher, they have the same IP address with different ports and fake player counts, literally thousands (more below)
4. Valid query ports are open and can be queried for every "real" server I tested and should be showing up.
5. This data below was obtained from querying the steam master server for DayZ servers. It is timing out so there is more then what is in this list. You can verify yourself by opening up the launcher and seeing all these, you will easily find these worst offenders. The attached upload is what was returned. My server is in this list as are many real servers that do NOT show up in the launcher as they should. Valid query ports are open and can be queried for every "real" server I tested.
