Unsupported record version SSLv2Hello using CloseableHttpClient

Question

I am trying to make an https call and getting the following error: Unsupported record version SSLv2Hello

Can anyone please shed some light on what I\'m doing wrong?

Answer 1

Figured it out. The two places I tripped over my shoelaces were:

Needed to register https with the PoolingHttpClientConnectionManager

Set TLSv1 as the only supported protocol in the SSLConnectionSocketFactory
