Fluentd SSL client hello handshake is randomly performed with TLS1.0 protocol

[deepaksb2]

What is a problem?

We have one target where we are invoking rest API post method using http plugin, sometime the request is failing during SSL handshake and getting below error intermittently (the server certificates are self signed certificates). Please help me how to resolve this issue.

"error"=>"SSL_connect SYSCALL returned=5 errno=0 state=SSLv3/TLS write client hello"

upon investigation I captured the network traffic logs through wireshark and found the call is failing whenever fluentd initiate the client hello request with TLS1.0 protocol while server certificates are configured with TlS1.2/1.3.
Below is the wireshark trace screenshot
