Hi. Thanks for replying.
I read it in two places. Here are the links.
1.
http://serverfault.com/questions/436737/forcing-a-particular-ssl-protocol-for-an-nginx-proxying-server
2.
http://w3facility.org/question/forcing-a-particular-ssl-protocol-for-an-nginx-proxying-server/

The full error is this: *peer closed connection in SSL handshake while SSL
handshaking, client: <client_IP>, server: <Server_FQDN> request: "POST
/Microsoft-Server-ActiveSync?Cmd=Ping&User=<domain>%5C<user_name>&DeviceId=SEC090121863242D&DeviceType=SAMSUNGSMT800
HTTP/1.1", upstream:
"https://SERVER_IP:443/Microsoft-Server-ActiveSync?Cmd=Ping&User=
https://SERVER_IP:443/Microsoft-Server-ActiveSync?Cmd=Ping&User=<DOMAIN>%5C<USER_NAME>&DeviceId=SAMSUNGSGHI337",
host: "<SERVER_FQDN>"*

produced with debugging enabled.


If I run *openssl s_client -connect <SERVER_IP:443* I get:
CONNECTED(00000003)
675508300:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake
failure:/usr/src/secure/lib/libssl/../../../crypto/openssl/ssl/s23_lib.c:184:
---
no peer certificate available

No client certificate CA names sent
---
SSL handshake has read 0 bytes and written 307 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE

If I run

*openssl s_client -connect <SERVER_IP:443 -SSL3 the connection works but it
won't work from nginx even when I enable SSLv3.*

*Hope I provided enough info. If not please let me know.*
