Technical breakdown: why HLSW fixes are mandatory
The official HLSW release had significant bugs, particularly affecting post-GoldSrc protocols. These fixes are mandatory for anyone serious about server monitoring or utilizing remote administration features.
Reliable Source engine RCON fix
A major pain point for server owners was the non-functional RCON on modern Source servers. This patch is vital for anyone managing games like Counter-Strike: Global Offensive (CS:GO) or Team Fortress 2.
- Problem: Previous versions failed to execute or maintain RCON commands due to outdated network protocol handling.
- Fix: The HLSW RCON fix within this update completely overhauls the communication protocol, ensuring full RCON functionality is restored across all supported Source engine titles.
Correct game identification (fixes HL2 detection)
The old code often miscategorized servers, leading to launch failures.
- Problem: Half-Life 2 (HL2) servers were incorrectly identified as classic Half-Life (HL) servers.
- Fix: The patched version accurately parses the Steam AppID information, guaranteeing correct server listing and eliminating errors when using HLSW to launch the game client.
Network polling stability for CS 1.6
Even for its original audience, this HLSW update improves the overall experience. The fix stabilizes network polling, providing real-time, accurate ping data essential for low-latency competitive play in Counter-Strike 1.6.

Query port requirement for specific servers
For stability on many non-Valve engines, you may need to manually specify the Query Port when adding the server in HLSW. This ensures accurate server monitoring.
Use the format:
$$[IP \:address]:[game \:port]:[query \:port]$$
Games often requiring this format include: 7 Days to Die, Battlefield: Bad Company 2, Hurtworld, and Natural Selection 2 (where the Query Port is typically the Game Port + 1).
