Issue Watchdog monit error in syslog

[heopas]

I am getting the following error in syslog

monit: Collector: cannot open a connection to http://127.0.0.1:2912/ -- Transport endpoint is not connected

I have found plesk official fix but it is for older versions. I have Version 17.5.3 Update #37, ‪CentOS Linux 7.4.1708

Enable Watchdog Extension and check that monit.service is up and running and port 2912 is open:

# systemctl status monit.service

# lsof -i tcp:2912
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sw-engine 10365 root 6r IPv4 248435071 0t0 TCP localhost:epicon (LISTEN)
