Hello Experts,

I am having issue to connect Heartbeat to Elasticsearch instance (Cloud).

Background:

I have a Linux server, Heartbeat Version 7.5.0 is running on it and sending Data to Elasticsearch instance (Cloud).  
But that Data is not picked up by Alerts (Rules) and clients don't get any alert email.

Elastic Cloud Instance is of latest version.

so to resolve this issue, I stopped Heartbeat Service for Version 7.5.0 and installed Heartbeat Version 7.16.3 on Linux server but it shows below error,

Expecting solutions from you experts 🙂

Hi @aji.shinde7,

There're serveral ways of connecting to an Elastic Cloud instance, can you please let us know whether you're setting the host directly in `output.elasticsearch.hosts` or using a combination of `cloud.id`/`cloud.auth`?

There shouldn't be an incompatibility so I'd recommend testing using `cloud.id` and `cloud.auth` as they are the [preferred](https://www.elastic.co/guide/en/beats/heartbeat/current/configure-cloud-id.html#configure-cloud-id) way to connect to cloud.

```auto
cloud.id: "<deployment id>"
cloud.auth: "<cloud auth>"

```

Hi emilioalvap,

I am using `cloud.id` and `cloud.auth`. Tried with 'output.elasticsearch.hosts ' as well. I am confused on using double quotes (") and certificate with extension ".pem"

I there something to do with SSL/TLS ?

Hi @aji.shinde7,

Config seems correct, it doesn't seem like the error would be related to heartbeat specifically.

Since this is happening on Elastic Cloud, could you open a [support request](https://cloud.elastic.co/help) for cloud team? They will be able to ascertain that all infrastructure elements are working correctly and. if needed be, reach out to us with more information.
