Hello,

I'm new to Elasticstack. I am using HTTP output plugin but am getting the following error:

```auto
[[main]>worker2] http - [HTTP Output Failure] Could not fetch URL {:url=>"https://{{fqdn}}:5059", :method=>:post, :message=>"Broken pipe (Write failed)", :class=>"Manticore::UnknownException", :will_retry=>false}

```

When attempting to CURL to the host, I get the following response:

```auto
NSS: client certificate not found

```

If I CURL to the host with -k included, it returns this:

```auto
NSS: client certificate not found (nickname not specified)

```

What causes the broken pipe error? Is this an issue with certs?
