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

[user3498724]

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).

Did you check that Apache is running?
# service httpd status
