Ruby: SSL_connect SYSCALL returned=5 errno=0 state=unknown state (OpenSSL::SSL::SSLError)

Question

Variants of this error have been posted all over the place but none of the solutions seem to work for me.

I\'m running ruby 2.2.2p95 (2015-04-13 revision 50295

Answer 1

I use Mechanize, and I was looking for a patch instead of a configuration of the http client instance. This is how I managed to do it:

OpenSSL::SSL::SSLContext::DEFAULT_PARAMS[:ciphers] += ':DES-CBC3-SHA'

Answer 2

This looks like exactly the same problem I've answered in https://stackoverflow.com/a/29611892/3081018. Same problem: the server can only do TLS 1.0 and only supports DES-CBC3-SHA as cipher. This cipher is no longer enabled by default in recent ruby versions. To connect with this cipher try to specify the cipher explicitly in your code:

http.ssl_version = :TLSv1
http.ciphers = ['DES-CBC3-SHA']
