Errors Poradniki

Some clients get 'This server is using a different protocol' because CS 1.6 has two engine protocols, 47 and 48. Understand which client uses which and accept both with dproto.

Why clients hang on 'Verifying and downloading resources', how the precache file limit and a broken FastDL cause it, and the fixes that let players finish loading in.

Why non-Steam players share STEAM_ID_LAN or get colliding IDs even with Reunion loaded, how the SteamIdHashSalt and cid modes work, why Reunion refuses to load without a long salt, and how to verify stable IDs.

What SZ_GetSpace and reliable-channel overflows mean, why too many entities or a chatty plugin trigger them, and how to cut the message volume that crashes clients.

What the game DLL is, why liblist.gam points at the wrong file, the Metamod hand-off that breaks the path, 32-bit and ReGameDLL mismatches, and reading the load error verbatim.

What AMX_ERR_NATIVE means, how to enable debug to see which native failed, and the usual triggers: invalid player indexes, a missing module, and bad parameters.

The 'Invalid STEAM UserID Ticket' kick means the server rejected the client's Steam auth. Either allow non-Steam clients with Reunion/dproto, or fix the Steam auth path. Both covered.

What 'Reliable channel overflowed' really means, which plugins and HUD/menu spam cause it, and how to stop the per-client netchannel from bursting past its buffer.

A methodical checklist for a CS 1.6 server that runs fine but never appears in the internet server browser: sv_lan, heartbeats, inbound UDP, NAT, and the master server.

How to make HLDS produce a core file, load it in gdb, read the backtrace to find which module crashed the server, and turn that stack into an actionable culprit.

Why SteamCMD hangs with 'Timeout downloading. Retrying', the app 90 legacy-depot trap for CS 1.6, and the retry, platform and CDN fixes that finish the install.

Why the server crashes on boot after mixing ReHLDS and ReGameDLL builds, how the API version handshake works, reading the console banner and crash line, and how to get onto a matched set.
