<div>
<div dir="ltr">Hi there,
<div><br>
</div>
<div>I am attempting to use the ssl module in order to get a socket to a remote server (MongoDB). I am using the following line of code (OTP 19)</div>
<div><br>
</div>
<div>ssl:connect("<a id="m_-1004493557143768437m_-8198080109616999013gmail-m_-3064993082963663185m_8506641838426673912m_5777177461594144945m_-8708617999540836611LPlnk803551" href="http://my-server.net" target="_blank">my-server.net</a>", 27017, [binary, {active, false}, {packet, raw}], 5000).</div>
<div><br>
</div>
<div>Whenever I use this, I get the following:</div>
<div><br>
</div>
<div>
<div>=ERROR REPORT==== 20-Dec-2016::19:13:13 ===</div>
<div>SSL: certify: tls_connection.erl:603:Fatal error: handshake failure - malformed_handshake</div>
<div>{error,{tls_alert,"handshake failure"}}</div>
</div>
<div><br>
</div>
<div>Which lead me to look into erlang:get_stacktrace/0</div>
<div><br>
</div>
<div>
<div>erlang:get_stacktrace().<br>
[{tls_connection,start_fsm,8,</div>
<div> [{file,"tls_connection.erl"},<wbr>{line,79}]},</div>
<div> {ssl_connection,connect,8,</div>
<div> [{file,"ssl_connection.erl"},<wbr>{line,84}]},</div>
<div> {erl_eval,do_apply,6,[{file,"<wbr>erl_eval.erl"},{line,674}]},</div>
<div> {shell,exprs,7,[{file,"shell.<wbr>erl"},{line,686}]},</div>
<div> {shell,eval_exprs,7,[{file,"s<wbr>hell.erl"},{line,641}]},</div>
<div> {shell,eval_loop,3,[{file,"sh<wbr>ell.erl"},{line,626}]}]</div>
</div>
<div><br>
</div>
<div>My problem is that the certificate that the server is using should be legitimate. I can connect, without error, using other clients and languages.</div>
<div><br>
</div>
<div>I took a look through Wireshark in order to try and figure out what is going on and this is what I see.</div>
<div><br>
</div>
<div>* The Client says hello and presents a list of cipher suites.</div>
<div>* The Server says hello and says that it wants to use TLS_RSA_WITH_AES_256_GCM_SHA38<wbr>4 (This cipher is in the list that the client sends)</div>
<div>* The Server sends the Client the certificates it is using (these both appear to be signed by DigiCert).</div>
<div>* The Server sends an encrypted handshake message.</div>
<div>* The Client responds with a Fatal Alert stating a Handshake Failure.</div>
<div>* The Server sends another encrypted handshake message.</div>
<div><br>
</div>
<div>I have verified that ssl:connect/4 is working fine as I can connect to a number of different miscellaneous services (including a number of other MongoDB instances).</div>
<div><br>
</div>
<div>I was wondering if there is anything else I can do to try and figure out why erlang does not allow this connection.</div>
