Warmane: new accounts fail auth with platform=Mac (LOGON_PROOF 0x09)

[silentcoder84]

Problem

New Warmane accounts (created in 2025-2026) fail to authenticate when using platform=Mac. The LOGON_CHALLENGE succeeds (server returns B, g, N, salt as expected), but LOGON_PROOF is rejected with result=0x09. Switching to platform=Windows makes auth succeed, but then Windows Warden kicks the bot within seconds.

Old accounts (created ~2020 or earlier) continue to work fine with platform=Mac.

What I've verified

• SRP6 math is correct — proven by old accounts authenticating successfully with the exact same code path
• Same g=7, same N, same code, same password — only difference is account age
• Tried all case combinations for account/password — all fail
• Changing password on Warmane website doesn't help
• platform=Windows auths successfully on the same new account, confirming credentials are correct
• Built a transparent auth proxy to capture the real WoW client's LOGON_CHALLENGE — confirmed client sends os=Win while wowchat sends os=OSX

Reproduction

1. Create a new account on warmane.com
2. Configure wowchat with platform=Mac (default)
3. Connect to Icecrown → "Invalid realm version" or auth rejection
4. Change to platform=Windows → auth succeeds, then "WARDEN ON WINDOWS IS NOT SUPPORTED" and disconnect

Related issues

• Warmane Icecrown Linux - invalid realm version #129 — same problem, no resolution. User reports "Old account still works, and we can't do anything until Warmane makes some updates."
• WoWChat won’t start on Warmane for newer accounts (only works on my main from 2020) #132 — "WoWChat won't start on Warmane for newer accounts (only works on my main from 2020)"
• Warmane Onyxia realm character not found #118 — Onyxia realm explicitly blocks Mac platform

Theory

Warmane appears to compute/store the SRP6 verifier differently based on the platform field in the LOGON_CHALLENGE, or outright rejects Mac platform for accounts that were first authenticated from a Windows client. Since web registration likely defaults to a Windows verifier, new accounts are locked to Windows.

The only accounts that work with Mac are ones that were first-authed as Mac (either via wowchat/headless bot or a native Mac WoW client) before Warmane tightened their restrictions.

Question

Has anyone found a workaround? Specifically:

• Is there a way to "register" an account as Mac-compatible on Warmane?
• Has anyone successfully handled Windows Warden to stay connected?
• Does the fjaros quote about accounts "magically working one day" have any known trigger?

Thanks for the GPT write-up. The answers remain the same - we don't know. We don't have access to warmane code and I doubt devs will help you unless you can bribe one.
