Why getting this error : option strike price basd on ltp?

I am getting error when trying to sell Banknifty CE 26300 or CE 27200 with current strike price at around 26800.

Why I am getting this error?

Error: Option Strike price based on Ltp percentage for entity account - ( my account ) across exchange across segment across product

what does this mean?

was this problem before also or is some new, NSE or SEBI rule?

EDIT:

Just checked, getting this error on buy orders as well. So we cant trade on just any option now but only a select few?

@siva

kind of got the answer but still not satisfied : Order Rejected RMS Rule

I guess this problem is particular with zerodha. I just placed order (sell banknifty ce 26200 @ strike price around 26790) with sharekhan and it went through easily.

So would there be any workaround for this here?
