Sorry for the late response. The steps you described should usually not cause you any trouble. You did not mention whether or not you did a reboot after expanding the filesystem, that should be done. Also, you might want to try using the port directly. Since you can access the M2P web interface you should also be able to access the SB Server’s. The Server’s web interface can be reached under the port 9000. So you need to type your device’s IP:9000 in the URL bar or your device’s name:9000 should also do the trick.
