IRCTC/Online Complaint Book — unable to book tickets in tatkal

I am waited almost more than a hour to book the tickets in tatkal but whenever it goes to payment page it returns back it did happened more than 2 times and available tickets in tatkal went to waiting list category this happened just after the tatkal category opened within 2 to 3 mins of time.

We would like to request irctc what would be the best possible option to book tatkal tickets as the opened tickets of 200 goes off in just minutes.
