Elastic Cloud Server (ECS)

HSS can run on Linux servers (such as CentOS and EulerOS) and Windows servers (such as Windows 2012 and Windows 2016).

The agent is probably incompatible with the Linux or Windows versions that have reached end of life. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.
