Does your cell phone have cookies enabled? Even if you accept the cert, the next time you log on it might ask you again. You might also need to update a app like taptalk or whatever you are using.
Wrong date, time zone and time can even cause it. There should be some setting you can adjust in your browser app like Enable/Disable Security Warning.
