IC-Card Authentication Trouble
Once an authentication error occurs on a browser, the browser saves that condition. Please do the following.
(1) Close the browser that showed an error.
If you have several tabs and windows open on your PC, please close them all. In Mac, select 'Close Firefox' from the menu, and close it. Even if you close all the windows with the 'x' button, the browser may not close.
(2) Confirm that the card reader is connected and the IC card inserted. Then activate the browser.
In case it won't help, please try clear he cache.
