We are running GroupWise webacces version 14.2.1 8/24/2016 .

Today we encountered a problem with a user.
He could work before noon.

In the afternoon, when he presses reply on a mail in the web client he gets:
your login is not current, Please login again

We have already:
-cleared the browser cache.
-tried another browser
-tried another pc with his login

The issue is there again.

Next step was a gwcheck , no errors present there.

Is this a bug ?
