Hi all!
first time poster here so please excuse my manners and correct me where
i am wrong.
I use NGINX 1.16.1 on Gentoo as reverse proxy server to expose some
services to an external web site.
I am exposing many things but one is giving me headaches.
I am trying to expose the web UI of an HP network printer.
I have this in my nginx.conf (trimming lines to the ones relevant):
server {
listen 80;
access_log /var/log/nginx/localhost.access_log main;
error_log /var/log/nginx/localhost.error_log debug;
location /printer/ {
proxy_pass http://192.168.1.XX/;
}
}
I can access the printer from the proxy server, no problems, with:
curl http://192.168.1.XX
But if i try, on the same proxy server this:
curl http://127.0.0.1/printer/
I get the error:
2020/03/06 08:42:02 [debug] 12870#0: *2 connect to 192.168.1.XX:80,

So my guess NGINX is doing something which the web printer does not
like...
What could i try or do?
thank you for your time and response.
