com.google.gdata.util.AuthenticationException: Unknown authorization header for GCalendar

We are using Google Calendar API v2 and V3 with authsub & 2LO and OAuth2.0 authentication for our customers. Most of our customers getting authorization exception frequently. Some are getting inconsistently from last one week. On analyzing our logs, the printstacktrace is

com.google.gdata.util.AuthenticationException: Unknown authorization header Unknown authorization header

Unknown authorization header

Error 401

at com.google.gdata.client.http.HttpGDataRequest.handleErrorResponse(HttpGDataRequest.java:608) at com.google.gdata.client.http.GoogleGDataRequest.handleErrorResponse(GoogleGDataRequest.java:564) at com.google.gdata.client.http.HttpGDataRequest.checkResponse(HttpGDataRequest.java:560) at com.google.gdata.client.http.HttpGDataRequest.execute(HttpGDataRequest.java:538) at com.google.gdata.client.http.GoogleGDataRequest.execute(GoogleGDataRequest.java:536) at com.google.gdata.client.Service.getFeed(Service.java:1135) at com.google.gdata.client.Service.getFeed(Service.java:998) at com.google.gdata.client.GoogleService.getFeed(GoogleService.java:645) at com.google.gdata.client.Service.getFeed(Service.java:1017)

Note: Using API v2 with authsub & 2LO about 2 years.

Any help would be appreciated.

Google Account Authentication APIs (ClientLogin, AuthSub and OAuth 1.0) are deprecated as per deprecation policy. http://googledevelopers.blogspot.com/2012/04/changes-to-deprecation-policies-and-api.html

Important: AuthSub has been officially deprecated as of April 20, 2012. It will continue to work as per our deprecation policy, but we encourage you to migrate to OAuth 2.0 as soon as possible
