Why I can't ever buy banknifty otm weekely options in zerodha.

Everytime I want to buy otm option like 200-300 strike away ,the order gets rejected citing RMS:Rule: Option Strike price based on Ltp percentage for Buy Orders . I'm almost never able to buy an option , let alone buy at a cheaper price when trend pullback occurs.It's happening since months. Is it specific to zerodha . Do customers with other brokerages experience the same?
