How can we connect two services running on different machines?

We have two services: counting and dashboard, which we have to run on different machines(different ip addresses).
We have successfully made these services talk to each other on same machine, but are unable to do so on different machines. The problems we figured out were-- while trying to connect the sidecar proxies for both the services, it is giving the error “connection refused”.

It would be great if someone can help me through this.

My service is present in 3 AWS regions and needs to do an application leader election within these three regions. I’m thinking of a 3 node setup (only one Datacenter) that spans across 3 regions with one node in each. This usecase is different from the common setup of multiple AZ used for nodes.

  1. Is there a better setup to do app leader election across 3 AWS regions?
  2. Does latency between regions affect HA in any way? Perhaps more false positive failures, but does it satisfy Raft’s correctness?
  3. What would my availability be with 3 nodes across these AWS regions? (Ideally want HA)

Are Consul Community Office Hours still a thing? Asking because this thread doesn’t seem very active.

Hi,
I have deployed Consul in Microk8s Cluster. I have 7 Nodes, everything is working fine but one day suddenly my server restarted and consul is stop working. I deleted the effected consul and restored from backup but the error is persist. I try to redeploy but have the same issue. I’m deploying consul via helm.
