SSL negotiate fail on api.binance.com

Hi

Since few days ago, our app fail to SSL negotiate with api.binance.com. It used to work well.

Now after connect, SSL handshake fails with following error message:
error:1408F10B:SSL routines:ssl3_get_record:wrong version number

Is there any change in Binance side? Can we still use http/1.1? Or is it now Binance restrict only to use h2 (http 2.0)?

Same code connect well to with www.google.com and we get following cipher:
Version: TLSv1.3, Cipher: TLS_AES_256_GCM_SHA384

Thanks & regards
