Peplink Balance 310 - No Access After Upgrade Firmware 6.1

Hi friends,
After I upgraded my Peplink Balance 310 from firmware 5.4.9 to 6.1, I cannot access controle panel.
After confirm the certificate, I received from browser (IE, Chrome and Firefox):
http://192.168.1.1/cgi-bin/MANGA/index.cgi
“404 Not Found”
Any idea?
Thanks in advance,
