Configure Nginx as reverse proxy with upstream SSL
I try to configure an Nginx server as a reverse proxy so the https requests it receives from clients are forwarded to the upstream server via https as well.
Here's the configuration that I use:
http {
# enable reverse proxy
proxy_redirect off;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwared-For $proxy_add_x_forwarded_for;
upstream streaming_example_com
{
server WEBSERVER_IP:443;
}
server
{
listen 443 default ssl;
server_name streaming.example.com;
access_log /tmp/nginx_reverse_access.log;
error_log /tmp/nginx_reverse_error.log;
root /usr/local/nginx/html;
index index.html;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_certificate /etc/nginx/ssl/example.com.crt;
ssl_certificate_key /etc/nginx/ssl/example.com.key;
ssl_verify_client off;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers RC4:HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
location /
{
proxy_pass https://streaming_example_com;
}
}
}
Anyway, when I try to access a file using reverse proxy this is the error I get in reverse proxy logs:
2014/03/20 12:09:07 [error] 4113079#0: *1 SSL_do_handshake() failed (SSL: error:1408E0F4:SSL routines:SSL3_GET_MESSAGE:unexpected message) while SSL handshaking to upstream, client: 192.168.1.2, server: streaming.example.com, request: "GET /publishers/0/645/_teaser.jpg HTTP/1.1", upstream: "https://MYSERVER.COM:443/publishers/0/645/_teaser.jpg", host: "streaming.example.com"
Any idea what I am doing wrong?
I found what was the error, I needed to add
proxy_ssl_session_reuse off;
In my case, I was trying to reverse proxy a website behind Cloudflare. I got the same error in /var/log/nginx/error.log
. I tried many solutions and this one worked for me:
proxy_ssl_server_name on;
yes even it's 2019 now some services still need SNI to distinguish among hosted sites.
