Why can't PDA log in?

From June 1, State Grid cooperated with the Ministry of Public Security to carry out information security attack and defense drills. In order to ensure the safety information leakage caused by some factors, the State Grid requires that some external interfaces be suspended. If you want to check the electricity bill or pay the bill, please go to the electric power business hall.

We are very sorry for the inconvenience. Thank you for your understanding.
