[Rspamd-Users] Unable to See Neighbours using a Load Balancer

Hello All,

I'm running into an issue with having the web UI show aggregated stats.

/local.d/options.inc

neighbours {
    server1 { host = "http://10.x.x.x:11339"; }
    server2 { host = "http://10.x.x.x:11339"; }
}

https://docs.rspamd.com/configuration/options/#neighbours-list

Each separate instance runs both rspamd and nginx, and I am able to query
the /neighbours endpoint on one instance successfully from another.
However, external traffic to each instance is directed solely by a load
balancer so when the browser attempts to query the /stat endpoint for each
neighbour it fails and the UI displays the errors below repeatedly.

"Cannot get server status"
"request failed"

These two instances are set up identically. The documentation doesn't seem
to note a way for the instances to interact directly; what is the solution
to resolve this setup with a load balancer so the instances are visible to
each other?

Thank you for your time,

Kendall
