Hello,
thanks again for your follow-up.
Indeed, it seems the port and uri was the issue, however I was not able to get the endpoint to work. I was able to get the authentication working and I am now able to connect using the CLOUD_ID and user/pwd.
If anyone else has the issue here is my code:
var authentication = new BasicAuthentication(USER, PWD); var client = new ElasticsearchClient(CLOUD_ID,authentication); var response = await client.CountAsync();
I will start experimentingwith the API which looks very powerful, I expect to easily be able to bulk insert in a flexible way.
