AUTOMATICALLY LOG OUT on as soon as try to click on any button

Pawan Mittal (CA Final) (702 Points)

05 December 2023 portal not working.  Unable to file online response of section 133c through the portal after login through TAN no. As soon as I click on any button on portal it shows me that "Your session has expired." 

please let me know the solution of the same problem. Because as soon as i login to that portal though TAN login then it does not allow me to do any activity. As i try clicDk on any button there. The message "Your session has expired."  appears on the screen and automatically log out.
