401 Error - Timestamp Expired
Error Code Cause
Users will see this error when they click a link to view a VitalSource eTextbook inside their LMS, but the LMS' server time does not match the VitalSource server time. Please note, the tolerance time is 5 minutes. This causes the server to reject the request, thinking it is an old or cached request.
Solution
Request that the LMS administrator corrects the time on the LMS server. It does not matter which time zone the server is in, as long as the time, date, and time zone settings are correct.
