Issues with cj webservices ReST API

Hi All

First post here and I am here about an issue with cj.com ReST API.

Basically, a percentage of all requests result in an Authorization fail . This percentage varies though seems to peek around 1 am UK GMT , about then There is a spell when all requests fail.

the cj support team have not responded and I wonder whether its my code or an issue on their side.

cheers
