Web interface is unavailable after update.

Hello!

After the last update of my camera the web interface stilling was unavailable. I try to connect to the device with by default URL (http://IP:81) but have no success. At the same time the device is available over of any applications (like a 'eye4' or 'vstarcam'). But it's not enough for the administration settings.
Can I downgrade the firmware at the factory default? How I can solve this issue?

Current version of the firmware: 48.53.75.113

With best regards,
greendruid
