Hi all, I have installed curator via RPM package on CentOS 6.7. I tried to delete some indices on elastic search. But when I tried to run curator, it gives error as below. 2017-06-13 15:13:21,660 DEBUG curator.cli cli: 135 action\_disabled = False 2017-06-13 15:13:21,660 DEBUG curator.cli cli: 139 continue\_if\_exception = False 2017-06-13 15:13:21,660 DEBUG curator.cli cli: 141 timeout\_override = None 2017-06-13 15:13:21,660 DEBUG curator.cli cli: 143 ignore\_empty\_list = False 2017-06-13 15:13:21,660 INFO curator.cli cli: 153 Preparing Action ID: 1, "delete\_indices" 2017-06-13 15:13:21,660 DEBUG curator.utils get\_client: 714 kwargs = {'hosts': ['127.31.21.47:9200'], 'use\_ssl': False, 'ssl\_no\_validat e': False, 'master\_only': False, 'client\_key': None, 'aws\_secret\_key': None, 'ce rtificate': None, 'aws\_region': None, 'http\_auth': None, 'client\_cert': None, 'u rl\_prefix': '', 'aws\_key': None, 'port': 9200, 'timeout': 30} 2017-06-13 15:13:21,664 DEBUG curator.utils get\_client: 764 Not using "requests\_aws4auth" python module to connect.

Just want to add something that I just found here. I did not have python installed, which python version I need to choose. ---

@theuntergeek Thanks for your reply. I have checked Elasticsearch via typing curl "127.31.21.47:9200" from the terminal, it runs well. I also checked the config.yml, like this: client: hosts: ["127.31.21.47:9200"] Why it cannot reachable? Thanks. ---

By changing the `logging:` block in your `config.yml` file to have `blacklist: []`, and `loglevel: DEBUG`, you will receive more debug information. I can't answer why `curl` works, and `Curator` can't. The error `Unable to create client connection to Elasticsearch.` is pretty clear, though. Please run with these settings changed, and include the last 20 or so lines of the log after attempting again. ---

It's quite clear that Curator cannot form a connection, regardless of what `curl` may reveal. On that subject, what do you see when you run `curl http://127.31.21.47:9200/`? ---

@theuntergeek I found the stupid mistake... I put 127 instead of 172... , now it's working. thanks so much. By the way, can you take a look at this question about elasticsearch?
