Why doesn't haproxy start as a service?

Question

CentOS

Hello.
it was necessary to configure and run haproxy as a user without sudo rights
, in general, it turned out to be done
/data/haproxy/haproxy -f /etc/haproxy/haproxy.cfg

[WARNING] 198/141606 (119143) : config : 'option forwardfor' ignored for frontend 'https-in' as it requires HTTP mode.
[WARNING] 198/141606 (119143) : config : 'option forwardfor' ignored for backend 'https-servers-basic' as it requires HTTP mode.
[WARNING] 198/141606 (119143) : config : 'option forwardfor' ignored for backend 'https-servers-redirect' as it requires HTTP mode.
[WARNING] 198/141606 (119143) : config : 'option forwardfor' ignored for backend 'https-servers-service' as it requires HTTP mode.

process started fine

[[email protected] haproxy]$ ps aux | grep haproxy
test   5109  0.3  0.0  49040  5224 ?        Ss   15:37   0:00 /data/haproxy/haproxy -f /etc/haproxy/haproxy.cfg

next I wanted to make a service
created in /etc/systemd/system
ha.service

[Unit]
Description=ha.service
[Service]
Type=simple
User=test
WorkingDirectory=/data/haproxy/
ExecStart=/data/haproxy/haproxy -f /etc/haproxy/haproxy.cfg
SyslogIdentifier=ha.service-log
Restart=always
[Install]
WantedBy=multi-user.target

Further

systemctl daemon-reload && systemctl start ha.service && systemctl status ha.service

As a result, the service starts and after a second it crashes.

What could be the reason and how to solve it?
