Hi @Manoj_Kumar9,

Where are you encountering this error? Which version of Elasticsearch and Kibana are you using?

Hi @carly.richmond

Thanks for the response.

I am trying out in my local instance with the version of 8.12.1 Elastic search and Kibana.

Please confirm we need to import any SSL certificate in kibana?

Hi @Manoj_Kumar9,

Are you running in an airgapped environment? I don't see any steps for installing certificates in the [getting started instructions](https://www.elastic.co/guide/en/machine-learning/current/ml-nlp-elser.html#elser-req).

Can you check you meed the minimum subscription and memory requirements as covered [here in the documentation](https://www.elastic.co/guide/en/machine-learning/8.12/ml-nlp-elser.html#elser-req)? Alternatively upgrading to the latest minor might be worth a try.
