certificate issue (3.0.1100)

Every time after I login to the GUI, there is an alert indicating pending certificate approval.  If I ignore it, the GUI will disconnect me after a few minutes.  I won't be ale to login again unless I close the GUI and relaunch.  If I approve the certificate, I can stay in the GUI longer.  However, when I login next time, there is pending certificate approval again.  Is the software designed to ask certificate approval every time you login GUI?
