Couldn't resolve host problem

[ghost]

Hi,

I have looked and this has been asked before but I haven't managed to get a complete fix for it - so far the only way I can resolve this issue is by commenting out the following lines of code in the Elastica/Transport/Http.php file:

// if ($response->hasError()) { // throw new ResponseException($request, $response); // }

    // if ($response->hasFailedShards()) {
    //     throw new PartialShardFailureException($request, $response);
    // }

    // if ($errorNumber > 0) {
    //     throw new HttpException($errorNumber, $request, $response);
    // }

This problem only happens when I am editing / adding a page etc. in the CMS when using Kunstmann CMS. Is this a versioning problem or a local env problem?

Thanks for your help in advance, and sorry if this is a duplicate.

Harry

@HarryWiseman If you comment out these strings, elastica works as expected? Could you please provide full exception trace and show us snippet of how you create instance of Elastica\Client?

@HarryWiseman Most interesting is probably the code where you add / edit the page. I'm curious if there is something that changes the host. Instead of commenting the code out above, can you post the full exception here?

And here is the exception stack trace:

there has been no set up for anything on my part I am using it with the Kunstmann package which comes with this pre configured.

Thanks,

@HarryWiseman Is the elasticsearch instance running on your local machine (localhost)?

[ruflin]

Closing as no updated provided. Please reopen if needed.

hi i have same, problem

1. elastic is not running on same machine
2. elastic is running, i can create any query through kibana
3. elastic is version 5.1
4. the error is number 6, and response is

Elastica\Response #b8e7 _queryTime protected => 2.5144689083099 _responseString protected => "" _error protected => FALSE _transferInfo protected => array (26) _response protected => array () _status protected => 0 _jsonBigintConversion protected => FALSE

[matak]

seems that url was defined with http:// sorry, you library add http to the uri

[rastafermo]

Sorry but I don't understand if this is solved or not. I have a similar problem and I can't find a solution. I've deployed a symfony project on heroku with an elasticsearch add-on up and running, but my symfony app could not resolve the host. Any hint?

[ruflin]

What is the error you get? What is your config? Did you try add / remove http:// etc?

[matak]

remove http:// from the config is enough, this solves the problem, but the elastica library automatically add to the url address http at the begining, we can close this topic

maybe add this note to the documentation, that the url should be defined without http
