Grafana Loki Microservices deployment - lots of got ping from unexpected node logs

I have setup a microservices deployment with individual rings for distributor, ingester and query scheduler components which is successfully ingesting logs and displaying them in grafana.

However, when I look at the individual component logs there are lots of Got ping for unexpected node warnings every second from different node IDs and local IPs my deployment is in. Any ideas on what to check or what might be causing this as I am worried it will cause issues down the line even though deployment appears to be working fine?
