Could not ping search engine: No alive nodes found in your cluster when node exists

I am having an issue where, when I try to reindex my site, I receive the following error:

Catalog Search index process error during indexation process:
Could not ping search engine: No alive nodes found in your cluster

The issue is, when I use Curl to check the same url in the config, it returns an active search instance.

Here is what I have so far:

Site is Magento 2.4.6, which uses Elasticsearch 8 according to documentation:
https://experienceleague.adobe.com/docs/commerce-operations/installation-guide/system-requirements.html
The instance I am using is Amazon OpenSearch 2.5, which is supported as of 2.4.6 as well.

Config in env.php:

        'catalog' => [
            'search' => [
                'engine' => 'elasticsearch8',
                'elasticsearch8_server_hostname' => 'https://mysearchurl.us-east-2.es.amazonaws.com', //Not Actual Url
                'elasticsearch8_server_port' => '443',
                'elasticsearch8_index_prefix' => 'test'
            ]
       

And when I run Curl with the url “https://mysearchurl.us-east-2.es.amazonaws.com:443” I get this (names and uuid values are modified):
