Receiving UNEXPECTED POOL ERROR when using Logstash with Elastic Cloud

I'm trying to set up my test instance for Elastic Cloud so my team can make a presentation to our management team to help in the decision on whether or not to move to the cloud offering however I am having problems getting my logstash instance to connect to my cloud based Elasticsearch instance.

Here is a typical configuration from my logstash.conf file:
elasticsearch {
hosts => ""
user => "logstash_ingester"
password => "xxxxxxxxxx"
index => "requestlog-%{+YYYY.MM.dd}"
document_type => "requestlogs"
sniffing => false

logstash_ingester is a custom user that I created and assigned it to the Superuser role.

The specific error that I am getting is this
UNEXPECTED POOL ERROR {:e=>#<LogStash::Outputs::ElasticSearch::HttpClient::Pool::NoConnectionAvailableError: No Available connections>}

followed by these two messages:

My cluster id is 8f56cc

Can you curl the cluster from the LS host?

Why does your log indicate that your Logstash instance is trying to connect to localhost? Do you have X-Pack installed? How have you set up Logstash? Are you sure it is using the correct config file?

That's what I couldn't figure out but then when you asked about x-pack the light bulb went on. I had installed x-pack for logstash but didn't uninstall it when I signed up for the Cloud trial. So uninstalled and logstash now appears to be working (will know for certain when I can get in Kibana and continue setting things up).

Thanks for the assist.
