Hi,

I am trying to connet to a site using https protocol and I get error:
$ erl -noshell -s inets -s ssl   -eval 'ok= httpc:request(get, {"
https://github.com/rebar/rebar/wiki/rebar", []}, [], [{stream,
"./rebar"}])'   -s init stop


{"init terminating in
do_boot",{{badmatch,{error,{failed_connect,[{to_address,{"github.com",443}},{inet,[inet],{eoptions,{{{badmatch,<<0
bytes>>},[{ssl_handshake,dec_hello_extensions,2,[{file,"ssl_handshake.erl"},{line,1737}]},{ssl_handshake,decode_handshake,3,[{file,"ssl_handshake.erl"},{line,926}]},{tls_handshake,get_tls_handshake_aux,3,[{file,"tls_handshake.erl"},{line,155}]},{tls_connection,next_state,4,[{file,"tls_connection.erl"},{line,433}]},{gen_fsm,handle_msg,7,[{file,"gen_fsm.erl"},{line,503}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}]},{gen_fsm,sync_send_all_state_event,[<0.54.0>,{start,infinity},infinity]}}}}]}}},[{erl_eval,expr,3,[]}]}}

I fed the ssl versions options to ssl option in httpc:

$ erl -noshell -s inets -s ssl -ssl protocol_versions '[tlsv1]'   -eval
'ok= httpc:request(get, {"https://github.com/rebar/rebar/wiki/rebar", []},
[{ssl, [ {versions, [tlsv1]} ]}], [{stream, "./rebar"}])'   -s init stop

and  I get the same error.

githum.com does not serves sslv3 connections anymore, but google.com does
and I get the same error (more detailed) :
