Is that the correct port? Are you running SSL? Do you have a firewall?

when I run that against mine

curl -u admin:admin -H "X-Requested-By: ambari" -i -X GET -k http://princeton0.field.hortonworks.com:8080/api/v1/clusters/princeton0

I get a ton of JSON

...

}, { "href" : "http://princeton0.field.hortonworks.com:8080/api/v1/clusters/princeton0/alert_definitions/83", "AlertDefinition" : { "cluster_name" : "princeton0", "id" : 83, "label" : "Ambari Server Alerts", "name" : "ambari_server_stale_alerts" } } ], "artifacts" : [ ]

@JJ

You seems to be hitting the Cloud Manager URL. https://ambariserver1.cloudapp.net:8440

1. Please check if your ambari is actually running on HTTPS or not? And what is the SSL Port.

# grep 'ssl' /etc/ambari-server/conf/ambari.properties
api.ssl=true
client.api.ssl.port=8443

If the grep 'ssl' does not return any value then it means your ambari server is not listening on Secure Port.

2. Check on which port the ambari server listening to:

# netstat -tnlpa | grep `cat /var/run/ambari-server/ambari-server.pid`
tcp6       0      0 :::8080                 :::*                    LISTEN      27953/java          
tcp6       0      0 :::8440                 :::*                    LISTEN      27953/java          
tcp6       0      0 :::8441                 :::*                    LISTEN      27953/java

Ambari Server uses the following ports:

8440 (https): Handshake Port for Ambari Agents to Ambari Server.

8441 (https): Registration and Heartbeat Port for Ambari Agents to Ambari Server

8080 (http): Interface to Ambari Web and Ambari REST API

3. So please check what is the client API port. Usually it is 8080.

4. Now try accessing the Rest Call on Rest Port.

Try using Hostname:

# curl -u admin:admin -H "X-Requested-By: ambari" -i -X GET  http://ambariserver1.cloudapp.net:8080/api/v1/clusters/hdptest
(OR)
# curl -u admin:admin -H "X-Requested-By: ambari" -i -X GET -k https://ambariserver1.cloudapp.net:8443/api/v1/clusters/hdptest

Try using IP Address of Ambari Server as well.

# curl -u admin:admin -H "X-Requested-By: ambari" -i -X GET  http://10.10.10.10:8080/api/v1/clusters/hdptest
(OR)
# curl -u admin:admin -H "X-Requested-By: ambari" -i -X GET -k https://10.10.10.10:8443/api/v1/clusters/hdptest

Assuming that 10.10.10.10 is your ambari server ip address.

If your Ambari Server is running on 8443 port (https) for Rest APIs then replace 8080 with 8443 and then try.
