Events Service Unhealthy

[SalahKhattab]

Hi,

I just started to implement a Cluster of 3 nodes of events service with a load balancer,
every node is started to be healthy and then unhealthy for two properties, and then go down

[Elasticsearch] unhealthy...retrying it the same error in every node and then go down

 I tried to build this cluster on Windows Environment

I tried to make a single node on the test environment also on windows, and it's running successfully.

Hi @Salah.Tarek Khattab,

"we should scale up the events service as long as we run it as a single node especially in the dev & test environment however it's recommended to use a cluster of multi-nodes in a production environment

there is no solution in this link,

it's only a question

Hi @Salah.Tarek Khattab,

I found this existing post where a member shared a similar error message. Can you check it out and let me know if it helps.
