nginx via systemd socket activation timeout error

Hi,

I'm trying to get nginx to be activated via a systemd socket as described in the wiki.

This service file works perfect when started via `systemctl start nginx.service`.

[Service]
User=http
Group=http
NoNewPrivileges=yes

CapabilityBoundingSet=
CapabilityBoundingSet=CAP_NET_BIND_SERVICE
AmbientCapabilities=
AmbientCapabilities=CAP_NET_BIND_SERVICE

# pid file
PIDFile=/run/nginx/nginx.pid
ExecStart=
ExecStart=/usr/bin/nginx -g 'pid /run/nginx/nginx.pid; error_log stderr;' 
ExecReload=
ExecReload=/usr/bin/nginx -s reload -g 'pid /run/nginx/nginx.pid;'

If I change the service file to

[Service]
User=http
Group=http
NoNewPrivileges=yes

Environment=NGINX=3:4;
PrivateNetwork=True

# pid file
PIDFile=/run/nginx/nginx.pid
ExecStart=
ExecStart=/usr/bin/nginx -g 'pid /run/nginx/nginx.pid; error_log stderr;' 
ExecReload=
ExecReload=/usr/bin/nginx -s reload -g 'pid /run/nginx/nginx.pid;'

And add a socket file

[Socket]
ListenStream=0.0.0.0:80
ListenStream=0.0.0.0:443

[Install]
WantedBy=sockets.target

Then the socket will listen and also start the service when I `curl localhost`, but nginx only timeouts:

I cannot interpret where the problem lies. Can someone point me in the right direction?

Best regards
