You need to check your configuration file because your daemon does not start.
Might come from a simple typo.
To test your haproxy configuration you can use the following command:
/usr/sbin/haproxy -c -V -f /etc/haproxy/haproxy.cfg
If you do not know the exact path to haproxy you can use the "which" command.
Usage and more parameters of haproxy can be found with haproxy --help.
Usage : haproxy [-f <cfgfile|cfgdir>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ]
[ -p <pidfile> ] [ -m <max megs> ] [ -C <dir> ] [-- <cfgfile>*]
-v displays version ; -vv shows known build options.
-d enters debug mode ; -db only disables background mode.
-dM[<byte>] poisons memory with <byte> (defaults to 0x50)
-V enters verbose mode (disables quiet mode)
-D goes daemon ; -C changes to <dir> before loading files.
-W master-worker mode.
-Ws master-worker mode with systemd notify support.
-q quiet mode : don't display messages
-c check mode : only check config files and exit
-n sets the maximum total # of connections (uses ulimit -n)
-m limits the usable amount of memory (in MB)
-N sets the default, per-proxy maximum # of connections (0)
-L set local peer name (default to hostname)
-p writes pids of all children to this file
-de disables epoll() usage even when available
-dp disables poll() usage even when available
-dS disables splice usage (broken on old kernels)
-dG disables getaddrinfo() usage
-dR disables SO_REUSEPORT usage
-dr ignores server address resolution failures
-dV disables SSL verify on servers side
-sf/-st [pid ]* finishes/terminates old pids.
-x <unix_socket> get listening sockets from a unix socket
-S <bind>[,<bind options>...] new master CLI
