Hi - We are using Nginx as a reverse proxy with SSL as a termination point
Call flow
Network Load Balancer (TCP) --> Nginx(SSL Termination) --> Vertx Servers
(HTTP)
This is the config we use, fairly standard
upstream xyz {
server 127.0.0.1:8080;
keepalive 4096;
}
server {
listen 80;
listen 443 ssl;
ssl_certificate /etc/ssl/certs/bundle.crt;
ssl_certificate_key /etc/ssl/private/nginx-digicert.key;
# ssl_handshake_timeout 10s;
ssl_session_cache shared:SSL:20m;
ssl_session_timeout 4h;
# ssl_handshake_timeout 30s;
server_name _;
root /usr/share/nginx/html;
access_log /var/log/nginx/raps-access.log timed_combined buffer=8k
flush=1m;
#access_log off;
# only log critical errors
error_log /var/log/nginx/raps-error.log info;
location / {
proxy_pass http://xyz;
proxy_pass_request_headers on;
proxy_ssl_server_name on;
proxy_http_version 1.1;
proxy_ssl_session_reuse on;
proxy_set_header Host $host;
proxy_set_header Connection "";
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
We see a lot of SSL handshake errors
