magento2 – configuring elasticsearch in 2.4.0

I installed magento 2.4.0 on sheared hosting with 1 click installation.

I understand that Magento 2.4.0 needs Elasticsearch to operate properly and I have set up an instance with AWS and I’m now trying and failing to configure my magento installation to connect to it.

I’ve entered the credentials into the back end but I’m still getting an error message about no active nodes on my cluster
