I am building a monitoring system by installing the monit package on Ubuntu, but I cannot connect to the monit web interface.

Port 2812 is in Listen state and the monit monitoring system runs normally. There are no firewall settings either. (This status allows all requests.) However, only the web interface is not connected.

The monit settings were as follows.

~/monit/monitrc set httpd port 2812 use address 0.0.0.0 allow my.website.ip allow 0.0.0.0/0 Other settings were not changed.

And sudo systemctl restart monit I ran the command and checked the log that it was executed normally.

What is the problem??
