Nginx redirecting too many times - nginx

Question

I am running into an issue where nginx is somehow redirecting over and over but I don't understand why:
server {
listen 80;
server_name splunk.trever.me;
return 301 https://splunk.trever.me$request_uri;
}
# Port 443 https config
server {
listen 443 ssl http2;
server_name splunk.trever.me;
location / {
proxy_buffers 16 4k;
proxy_buffer_size 2k;
proxy_pass http://10.0.1.1:8000;
}
access_log /var/log/nginx/splunk.trever.me/access.log;
error_log /var/log/nginx/splunk.trever.me/error.log;
}
Am I missing something here? I looked at all the documentation and it doesnt seem to be wrong. Does this mean something upstream is sending the browser back to http?

Answer 1

use this:
server {
server_name splunk.trever.me;
if ($http_x_forwarded_proto = "http") {
return 301 https://$host$request_uri;
}
location / {
proxy_buffers 16 4k;
proxy_buffer_size 2k;
proxy_pass http://10.0.1.1:8000;
}
access_log /var/log/nginx/splunk.trever.me/access.log;
error_log /var/log/nginx/splunk.trever.me/error.log;
}

You can redirect the requests using the IF directive in nginx config.
server {
listen 80;
listen 443;
server_name splunk.trever.me;
if ($scheme = http) {
rewrite ^/(.*)$ https://splunk.trever.me/$1 permanent;
}
location / {
proxy_buffers 16 4k;
proxy_buffer_size 2k;
proxy_pass http://10.0.1.1:8000;
}
access_log /var/log/nginx/splunk.trever.me/access.log;
error_log /var/log/nginx/splunk.trever.me/error.log;
}
