I am new to Elasticsearch. I have Elasticsearch (Self-Managed) deployed on Azure. esdata0 and esdata1 Azure Linux VM. I am able to connect esdata0 via SSH through PuTTy on my pc. Because esdata0 has a public IP. I cannot connect to esdata1. I only see a private IP for esdata1. I don't understand the architecture behind it. Would you please help me with this?
