Deploying Machine Learning Model Fails with SSL ERROR

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
Opensearch version v 2.19.1Running on RHEL 9

Describe the issue:
We are trying to deploy a Machine Learning Model to our cluster but we are receiving the following error:
unable to find valid certification path to requested target

Both Opensearch and Opensearch Dashboards are running on the same server with the same certs.
I put the model zip file on the same host available via a url, again using the same certs and am seeing that error.

Not sure where to go so any help would be appreciated!

Please let me know if there are any relevant files/configs that would help inform the issue.

Thanks!
