Error 30500 – Internal Server Error. Please retry your last operation.

Hi Experts,
I received an error message on my Book Live (running Software Release 2.0 or higher) Remote Web Access.
It is indicating internal server error. I tried several ways to get a remedy of this issue but failed.
I have recently installed the software My Book live with software release 2 and it was installed successfully but when I try to set up a remote web access or when generating a code for mobile access, I get an error.
Have you any idea for the issue?
Please help.
Thanks in advance.
