Why did I remind me that my authentication failed when I booked a ticket in Ctrip?

How to deal with this situation:

1, you can quit the software and try again.

2. If it doesn't work, it may be because it's the end of the year, in order to control scalper scalping and improve safety procedures.

3. I need you to resubmit and verify your personal information, including your phone number and other personal information. I ordered a high-speed train the other day.

The same is true of tickets, just re-verify them.
