Huawei Access Manager Error 777

For the previous days, I've been receiving faulty information that says "Error 777: The connection attempt failed because the modem (or other connecting device) on the remote computer is out of order." I am connected to the internet. I have Huawei Access Manager and it is connected to the internet since I am using Tata Photon which is also from Huawei. This problem mostly occurred during night time. As I am trying to connect again, the same error message just keeps on popping up. What can I do with it?
