I just noticed that one of my VMs can't report metrics because of a "failed ping for metrics on peer address 10.xx.xx.xx socket: permission denied" error in the logs. How can I fix this permission denied error?

ICMP must be enabled on the machine to report metrics

What do you mean by ICMP must be enabled? Running the ping command on the machines works just fine

Is this running netclient in a container (docker)?

No it’s running on Debian machines installed via apt
