Request Munchkin ID approval for Beta?
It looks like I’m connecting but it times out. Per Claude, it is an access issue:
This points to the beta allowlist. Your Munchkin ID likely hasn't been approved yet, so the server times out during the auth handshake rather than returning a clean error.
Here’s the log history (I xxx out the ID, secret, etc.):
