Problems with Proxy implementation

NethSecurity
1

NethServer Version: NethSecurity 8-24.10.0-ns.1.5.1
Module: proxy

hi all!

i’ve set up the same exact proxy i had on my nethserver 7, imported the correct certificates as it should be, now when i test the proxy i get an nginx error 502 for some reasons i can’t understand how to fix.

how can i help you help me trying to figure out why the same exact proxy used in the nethserver 7 doesn’t work on nethsecurity 8? it’s a really simple implementation that should be almost plug and play but i don’t understand what breaks stuff. i’m not in production and i’m just in a test inviroment at the moment

another useful piece of information:
both the Nethsec and the server i need to reach are in the same DMZ
the nethsec has just one LAN setup
this setup was working fine on nethserver 7

Usually the 502 bad gateway error means that the server at the destination URL doesn’t respond.

Is the destination reachable from the nethsec? You could check using curl:

curl 192.168.0.10:2345

yes i can reach through curl the destination server which is on the same exact subnet of my nethsec.

Maybe you need to setup a DNS A record for the domain name to point to the NethSec IP?
