That would be a great relief also for our DM server as well if you could somehow fix or speed that up!

Hello,
We also tested this issue ~two days ago on a test server because our community reported it.
It didn't work in Cherno either, but it worked in Berez and Electro.

I can confirm, removed your .pbo with the update and had 3 crashes since.
It improved a lot but in some cases its still happening.

It seems that some fixes have been applied, please check if you can find your servers among the community servers.

Here is a pretty simple php script to query the valve master server and also the answer you get. (message.txt)
I get a correct response from valve every time with ALL the servers I'm missing in the DayZ ingame Launcher. (tested the script on several locations all over Europe - same result)

Hello

The trouble also is that there's other factors that can cause spurious results and it's hard to untangle those because many people don't even know about them

Your Official Community server list can be corrupted by your steam effectively over stressing your router by pinging too fast, that sometimes needs a little choke/throttle in this place, and turning it down can get better results

It's very hard to untangle many things

I'm still missing lots of servers I'm usually playing on.
I can add them to my favorites via direct connect -> recent -> favorite workaround, so they are online and reachable but they are not findable in the Community Tab.

Got the same Problem, seems like they already fixed it for some but not for all.
