Hello,

I have a problem like issue #1125
On CloudLinux 8.9.1 and cPanel/WHM 116.0.10 with Engintron 2.2 I get Nginx v1.14.1 this error:
nginx[8076]: nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
nginx[8076]: nginx: configuration file /etc/nginx/nginx.conf test failed
systemd[1]: nginx.service: Control process exited, code=exited status=1
systemd[1]: nginx.service: Failed with result 'exit-code'.
systemd[1]: Failed to start The nginx HTTP and reverse proxy server.
systemd[1]: nginx.service: Unit cannot be reloaded because it is inactive.

I only changed custom_rules for Nginx:
set $PROXY_DOMAIN_OR_IP "123.45.67.89"

What I tried:
Enable ipv6 as mentioned before with method 2
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
But after rebbot nothing changed

Tried edit default.conf:
#listen 80 default_server;
listen [::]:80 default_server ipv6only=off;

change to

listen 80 default_server;
#listen [::]:80 default_server ipv6only=off;

As far nothing helped. If I uninstall Engintron everything is works.
What I missed?

Thank You
