Connection error while connecting to cloudant DB from localhost - nosql

Question

I am trying to connect to cloudantDB from local.
This is the code that I get from the IBM example and it is working on deployed version online.
try {
System.out.println("Connecting to Cloudant : " + user);
//This works
CloudantClient client = ClientBuilder.account(user)
.username(user)
.password(password)
.connectTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();
System.out.println("Connected to Cloudant : " + user);
//This doesn't works and fire the errror Show the server version
System.out.println("Server Version: " + client.serverVersion());
//This doesn't works and fire the error to. Show databases
System.out.println("Dbs: " + client.getAllDbs());
return client;
} catch (Exception e) {
throw new RuntimeException("Unable to connect", e);
}
And from localhost I have this error:

I'm not behind a proxy..
What am I doing wrong?

Answer 1

from cloudant console "generate api key" I get the account/password
and the database name
If you are using an API key then the account name is not the same as the username. In your example they are both called using user
ClientBuilder.account(account_name) // needs to be the part before .cloudant.com
.username(api_key_user) // needs to be the API key
Secondly, API keys are per database so don't have permission to do getAllDbs().
FWIW the .build() doesn't actually connect to Cloudant it just builds a CloudantClient object, no HTTP requests happen until needed.

Answer 2

Solved.
User and password MUST be created from Cloudant service -> Service Credntial -> New Credential.
I was using wrong credential created from the cloudant -> database -> permissions -> Generate API Key.
