Debugging connection issues

Please try the following steps if you have trouble connecting to your cluster:

1. Check if you can connect to your cluster on the commandline

Try to curl your cluster directly, for example

# curl an unprotected cluster
curl -X GET "http://localhost:9200"

# curl a cluster that uses ssl
curl -k -X GET "https://localhost:9200"

# curl a cluster that uses authorization
curl -k -X GET -u elastic:yourpassword "https://localhost:9200"

Proceed to the next step if you see a response similar to this one:
