Non-Steam masterservers do not list my ReHLDS server even though heartbeats and A2S_INFO responses work

[ElijonNikoliqi]

Description: I am trying to get my CS 1.6 server listed on Non-Steam master servers to attract players using different builds. I have a custom AMXX plugin that successfully sends heartbeats to a list of 61 master servers (Setti, Tsarvar, etc.), but the server is still not showing up in the "Internet" tab.

The Problem: My server is running ReHLDS with Reunion 0.2.0.25. Even though Reunion is running, the command dp_r_protocol returns 0. I believe this is why the master servers are rejecting my server, as they require a valid protocol (48/47) to list the server.

My Setup:

Engine: ReHLDS

Protocol Fix: Reunion 0.2.0.25

Connectivity: Ports are open (Server is visible on GameTracker).

Master Server List: 61 servers configured in setmaster.ini.

My Questions:

How can I fix Reunion so it correctly reports Protocol 48 instead of 0, so Non-Steam master servers will accept my heartbeats?

Are there any specific ReHLDS or Reunion settings required to make the server visible to Non-Steam master server browsers in 2026?

Is there a better way to "force" the server onto the master lists when using ReHLDS?

Current status: meta list shows Reunion is RUN. dp_r_protocol is 0. Server is Online, but invisible in the in-game browser in non-steam clients.
if anyone can help me i will apriciate it

Why are you requesting for help with pirated/non-steam clients here? This is Valve's official Half-Life 1 SDK repository, there will be no support for non-steam, ReHLDS or Reunion here. The game is currently on sale for 80% off, go buy it for $1.99.

Simple fix, first remove DProto/Reunion, so the server supports only Protocol version 48. All your problems will be solved, that I am certain of.

That is not a valid reason to support pirated version of the game. This is a public bug tracker for the Half-Life 1 SDK, it is not a forum, so it's the wrong place to ask for help in the first place. Reunion is a 3rd party Metamod plugin, you have to ask for help elsewhere, you won't get any help here.
