Simply, the first thing you can do is upgrade your JDK.
And the next thing is add your server's cert to client's trust store.

How about support testing option for TLS version? It will be applied to ngrinder http client as below.
https://www.baeldung.com/apache-httpclient-tls

Or .. make ngrinder httpclient only use TLS 1.2, 1.3

[imbyungjun]

If the protocol is HTTP/1.1, HTTP client will handle TLS with BasicClientTlsStrategy,
and if the protocol is HTTP/2.0, HTTP client will handle TLS with H2ClientTlsStrategy.
Both of them filters weak TLS protocol version TLSv1 and TLSv1.1 by using TLS.excludeWeak().

I don't understand that nGrinder HTTP client sends a request with TLSv1
