Endlessh "Failed to start Endlessh SSH Tarpit"

I have just learned about Endlessh package, I have installed following steps described in this video

But when it comes to check if Endlessh is listenning port 22 nothing happens, Then, I checked the status to see if it's running but it doesn't, here the result I have :

xxxxxxxxx@localhost:~$ sudo systemctl status endlessh.service

while looking further answers to my issue, I found on github of skeeto/endlessh, this :

I tried but I still get the same Failure status when restarting endlessh. I forgot to mention that I create a config file in endlessh folder /etc/endlessh/config:

# The port on which to listen for new SSH connections.
Port 22
# The endless banner is sent one line at a time. This is the delay
# in milliseconds between individual lines.
Delay 10000
# The length of each line is randomized. This controls the maximum
# length of each line. Shorter lines may keep clients on for longer if
# they give up after a certain number of bytes.
MaxLineLength 32
# Maximum number of connections to accept at a time. Connections beyond
# these are not immediately rejected but will wait in the queue.
MaxClients 4096
# Set the detail level for the log.
# 0 = Quiet
# 1 = Standard, useful log messages
# 2 = Very noisy debugging information
LogLevel 0
# Set the family of the listening socket
# 0 = Use IPv4 Mapped IPv6 (Both v4 and v6, default)
# 4 = Use IPv4 only
# 6 = Use IPv6 only
BindFamily 0

Do you have any ideas what is wrong ? should I restart the server ? Thank :)
