In our infrastructure, we have cluster of app nodes with consul service running as consul server component.
There is also another cluster of proxy nodes which have consul-template service installed. This consul-template has configuration which is used to discover the healthy app nodes and update the proxy config file.
We are using chef to provision our infra. The app nodes were configured properly. Consul service on these nodes is working as expected.
But on the proxy nodes when the consultemplate service is trying to start I see the following WARN in the messages log file:
[WARN] (view) catalog.datacenters: Get https://<app_nodes_consul_service_ip>/v1/catalog/datacenters: http: server gave HTTP response to HTTPS client (retry attempt 5 after "4s")
I am not sure what config on the app nodes - consul service I need to check to see why its responding as HTTP instead of HTTPS.
I dont want to change this to HTTP in the lower env as I want the chef cookbooks to be consistent across the envs including the HTTPS connecivtities.
Any pointers on which config I need to check would be of great help.
