Api futures kline data is not matching actual data in website

I am trying to get futures kline data for ADABUSD but data I got is not matching actual data shown in website. It is affecting RSI calculations too much and spoling my strategy. Is there any solution ? Or What I am doing wrong
I am using the following function in python.

client.futures_historical_klines(…)

can you please give us the data you seeing on the UI?

thanks
