one of the reason e.g. Arma 3 servers aren't scanned anymore
is that GameTracker isn't supporting new secure query of STEAMWORKS
(important as any insecure server is easily abused for reflection DDOS)

e.g. all up-to-date (official and community) servers of games like
Arma 3
DayZ
with enabled secure challenge are since invisible to GameTracker
e.g. from 6000+ public Arma 3 servers, GT doesn't know about 5000+
(e.g. only ~500 listed on GT)

note: this does apply to any CS/CSGO/TF2 etc. (STEAMWORKS) servers too
if such server enables the secure query challenge
then it cease to respond to obsolete requests w/o challenge support

so please read #1st post from Valve staff about new libraries introducing secure-challenge to query
https://steamcommunity.com/discussions/forum/14/2974028351344359625/

following URL is must read for developers of of 3rd party tools
to continue query game servers via STEAMworks after secure challenge is enabled

https://developer.valvesoftware.com/wiki/Server_queries#A2S_SERVERQUERY_GETCHALLENGE

if possible please update GameTracker
as more developers rolling those secure libraries out
until the insecure way is phased out as obsolete

Thank you.

Your comments have been passed on to the admin and developers.

Hello,

are there any news on this matter? It seems that Gametracker is still not able to scan updated Arma3-Servers (and HL/HL2 as it seems).

Best regards.

I have been given assurances that developers are working on the issues.
Developers do not give progress reports in the forums.
Any changes/fixes will be announced in the forums as they become available.


I would strongly recommend that server managers read this link to determine if you have options in the interim.

You must decide for yourselves what your priorities and risks may be given your particular circumstances.

As reported here...

https://www.gametracker.com/games/left4dead2/forum.php?thread=182886

...this issue also affects ALL servers running the latest Left 4 Dead 2 (L4D2) version (2.2.1.3) released 15-Jun-2021.

Hello, Valve has updated the Source-Query Protocols and this new Patch is applied for Left 4 dead 2 in the last update few days ago.

You have to update the php script that running the source queries according to Valve new changes :

As chimaera500 mentioned, we are aware of these updates and are currently looking into this issue. We will update this thread when more information becomes available.

Please note that the new code to resolve this issue has been available since last year.

Here is a link to PHP-Source-Query on GitHub which works with the "new" server query challenge:
https://github.com/xPaw/PHP-Source-Query/

Here is a link to the Valve specification:
https://developer.valvesoftware.com/wiki/Server_queries

It appears that Valve will eventually update most of their games to use the updated server query. Please help us understand why the long delay.

The developers now have all the information that they require to progress this issue.
The problem/update is in hand.

- Developers do not give 'progress reports' so please do not ask (requests of this nature will be deleted).

- We do not need a list of affected servers (any such posts/reports will be deleted).

- This thread will be updated by an admin/moderator/developer when a fix is in place for final testing.

An update has been pushed to account for the A2S protocol changes. GameTracker will now be able to scan servers using the updated Steam libraries.

Please let us know if you experience any issues.
