Hi,
You should first check your logs to validate that your configuration has really been taken into account. The logs will show you the value of RemoteAccessAllowed. I would also recommend to first disable authentication and reactivate it once you can access the explorer from remote. The browser might also display a login window when RemoteAccessAllowed is false.
Example of logs that you should see at startup once Authentication is disabled:
W1001 16:20:14.897346 main.cpp:1014] ====> Remote access is enabled while user authentication is explicitly disabled, your setup is POSSIBLY INSECURE <====
HTH
