Resolved connect() failed (111: Connection refused) while connecting to upstream

New Pleskian
Hello, I am using Plesk Onyx 17.8.11 on Debian 9.4, and have a (Hetzner CX20) virtual server with private ip address 172.31.1.100 configured 1:1 via NAT on public IP 88.99.186.220.

When trying to open my website www.1luxuryphones.com I am getting ‘502 bad gateway nginx error’, and can see the following errors in /var/www/vhosts/system/1luxuryphones.com/logs/proxy_error_log:

*2018/04/08 15:20:43 [error] 4568#0: 2721 connect() failed (111: Connection refused) while connecting to upstream, client: 77.98.74.207, server: 1luxuryphones.com, request: "GET / HTTP/1.1", upstream: "http://172.31.1.100:7080/", host: "www.1luxuryphones.com", referrer: "http://www.1luxuryphones.com/"

In Plesk panel > Tools & Settings > IP addresses I have configured IP 172.31.1.100 so it has external IP 88.99.186.220.
However based on the proxy_error_log above it seems there is nothing listening on 172.31.1.100:7080, so the nginx cannot successfully forward the traffic.

Would someone know if more configuration should be done in Plesk to fix this issue?

Many thanks
 
Please check your network-config:

/etc/sysconfig/network-scripts/

Check this and please make sure that the settings for the IP are as they should be.

You can be sure to put the PHP interpreter from FPM(Nginx) to FastCGI(Apache).
