no httpd connection for monit started from systemd

Question

When starting monit my logs show that

[CET Oct 31 19:43:34] info     : Starting Monit 5.16 daemon
[CET Oct 31 19:43:34] error    : monit: monit httpd not started since no connect allowed
[CET Oct 31 19:43:34] info     : 'srv.home' Monit 5.16 started

despite having

set httpd port 2812

in /etc/monit/monitrc.

Is there anything else needed to have the httpd server enabled when monit is started via systemd?

Note: A previous answer pointed to an extra and, which is not my case (the andwas there, but an an introduction for following configuration lines, of which I believe I need none for an open, unauthenticated access. I also tried to add and use address 10.10.10.254 to the line above expecting that this is the address the httpd monitor would bind to, unfortunately with the same effect)

I guess I've just hit the same issue. The question is old, but since I see no valid answer I've added mine. — Davide Cavestro, Mar 09 '18 at 09:04

It seems you have to specify at least one between the allow and credentials directives.

In my case I solved the issue simply adding the ALLOW directive

SET HTTPD PORT 2812
  USE ADDRESS 127.0.0.1
  ALLOW 127.0.0.1

See the relevant code from monit sources.

The monit http server is not responding until monit is fully started. It you specified an "start delay", the http server will not respond until that delay.
set daemon 120 # check services at 2-minute intervals # with start delay 240 # optional: delay the first check by 4-minutes but also responses from http server

no httpd connection for monit started from systemd
