In my server configuration, I use the local ddev url and export to config. Like this:
...
id: es_server
backend: opensearch
backend_config:
connector_config:
url: 'https://drupalorg.ddev.site:9201'
...
Then, I override the values per environment via $settings, like this:
$config['search_api.server.es_server']['backend_config']['connector_config']['url'] = getenv('SEARCH_API_HOST');
The reason for this set up is so I can change server URL, username, password or other settings via environment variables instead of having them exported in config.
Everything via the UI works as expected.
On production:
It doesn’t seem to be applying the configuration overrides via cron.
Closed: works as designed

Thanks to @larowlan for helping via slack to debug this.
It was not an issue here. drush cget search_api.server.es_server --include-overridden showed that the overrides I was setting were not actually being applied.
