Hi @gsmith

I checked the plugins version as you advised and they matched the Graylog version that I installed.

I also disabled HTTPS on the Opensearch cluster but unfortunately, I got exactly the same error message. This is a new fresh cluster. So I didn’t migrate any data. Is there anything else I need to check?
