Accessing prometheus metrics for opnsense plugin

I am running OPNsense 25.7.6-amd64 on FreeBSD 14.3-RELEASE-p4 with OpenSSL 3.0.18 and have installed the os-crowdsec 1.0.12 plug in. I have registered the security engine and enabled acquisition of caddy logs and certain selected loki logs. Notifications for telegram have been configured and tested. I have amended /usr/local/etc/crowdsec/config.yaml as follows and restarted the crowdsec service:

prometheus:
  enabled: true
  level: full
  listen_addr: 0.0.0.0
  listen_port: 6060

prometheus:
  enabled: true
  level: full
  listen_addr: 0.0.0.0
  listen_port: 6060

When I access my opnsense router at either http://192.168.1.1:6060/metrics or https://192.168.1.1:6060/metrics I receive a timeout error. What should the address be to expose crowdsec metrics for prometheus with the os-crowdsec plugin?

I searched on the discourse forums and in the discord. I reviewed the log files for any references. I followed the opnsense guide at https://docs.crowdsec.net/docs/getting_started/install_crowdsec_opnsense/.

OPNsense | CrowdSec

The CrowdSec plugin for OPNsense is installed from the official repositories.

@Instant Dreams you made sure to allow the port on your opnsense firewall to internal traffic?

Instant DreamsOP•2mo ago

That's an interesting idea. 192.168.1.1 should be on the LAN, but I'll add a floating rule for port 6060 and see what happens

Added a floating rule and applied it, waited, then tried again. Connection still timed out.

I had previously done a sudo service crowdsec reload so this time I also did a service restart from the GUI and metrics are now being served on http://192.168.1.1:6060/metrics I am going to remove the floating rule and restart the service to confirm if it was the rule, the gui restart, or both Testing: 1. Removed the floating rule and applied change to firewall - metrics served 2. Restarted crowdsec service via gui - metrics served I'll write this up on the forum This is resolved now
