I've been seeing a ton of info about reverse proxies and nginx but I'm a little lost on how to implement. I am running two separate EC2 instances (front and back end, with back end running pm2). I have SSL established on the front using LetsEncrypt, and it won't allow me to hit my backend because of Mixed Content. What should I do?
nginx.conf
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name domain;
location / {}
return 301 https://$host$request_uri;
}
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name localhost;
root /insert/root/here;
ssl_certificate "/path/to/cert";
ssl_certificate_key "/path/to/key";
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:SEED:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!RSAPSK:!aDH:!aECDH:!EDH-DSS-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA:!SRP;
ssl_prefer_server_ciphers on;
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
