--- Comment #5 from Hans Leidekker hans@meelstraat.net --- Can you try current git? Patches have landed today that may help. If it still fails please attach a WINEDEBUG=+secur32,+ntlm,+wininet,+winhttp,+rpc,+seh,+tid trace. Make sure to remove all occurrences of your credentials from the log before attaching it, including base64 encoded versions (look for Authorization: Basic headers).
