curl localhost:9877 error: Unknown SSL protocol error in connection to localhost:-9850

I'm trying to test some web services provided by a b2 on the DVM (9.1.201404.160205) before uploading to our staging environment, but I keep getting these SSL errors even with --insecure (-k):


$ curl  https://localhost:9877  -k -v

* Rebuilt URL to: https://localhost:9877/

*   Trying ::1...

* connect to ::1 port 9877 failed: Connection refused

*   Trying

* Connected to localhost ( port 9877 (#0)

* Unknown SSL protocol error in connection to localhost:-9850

* Closing connection 0

curl: (35) Unknown SSL protocol error in connection to localhost:-9850


I know that the cert is self-signed (and expired) -- but I thought that --insecure would cause that to be dropped. I've been playing with different switches to force various ssl/tls versions and ciphers (stack overflow had some advice that this error is related to an odd protocol/cipher combo on the server side), but alas I haven't hit the combo yet. had this to report:


--> Testing protocols (via sockets except TLS 1.2 and SPDY/NPN)

Local problem: /usr/local/opt/openssl/bin/openssl doesn't support "s_client -ssl2"

No further cipher order check has been done as order is determined by the client

--> Testing server defaults (Server Hello)

Strange, no SSL/TLS protocol seems to be supported (error around line 1803)



Does anyone know of a way to get it working?


Or maybe another thing to ask is - am I the only one who's having a problem? Does curl work for other folks against the DVM?


Note: this is a somewhat academic question, as I can successfully test against the DVM in a browser window via https://ws_user:ws_pass@localhost:9877/webapps/
