[ElasticSearch 7.6.2] Client requested protocol TLSv1 is not enabled or supported in server context

[Ahmed_Abdulaleem]

Good Day,

are there a way to force elastic search use TLSV1 when negotiating with client
the client is a web application running under IIS web server.

Error Log:
javax.net.ssl.SSLHandshakeException: Client requested protocol TLSv1 is not enabled or supported in the server context

It is disabled by default, and with good reasons. If you definitely can't enable your client application to support a safe TLS version , you can explicitly enable TLS V1.0
