Fail to access /usr/share/udhcpc/default.script, errno: 13 (Permission denied)

Hi, I am currently meeting this issue. I have followed the supplied guide and configured the kernel as well as tried this using modules.

The AT Commands work fine with obtaining HTTP requests, though I will need to make this work with QWWAN.

The module being used is:

Revision: EG21GGBR07A09M1G

Log from Qconnect is below.

Dear Moes,
Thanks for your inquiry in Quectel forum.
Please confirm whether the module already register on network successful before you dial up with QWWAN. From the log you provide, we can see following error information, so please double check it. Thanks!
