Greetings, I have a little service that pushes logs to Elasticsearch (1.4.2), and I am now using the [Elasticsearch.net](http://Elasticsearch.net) client (1.3.1). This is all running on my dev machine - 64 bit Windows 2008 R2, .Net 4.5. However, strange thing is happening depending on which user the service executes under: - It works fine when running as my domain user (company/me). - It fails the exception below, when running as a local user (./service\_user), which is the way I want it to run. - It fails the same way when running as the Local System user. Is a "Ping" just a HEAD request? That is what I am led to believe by having fiddler running. In which case when it does not work, there's no HEAD request made at all. So it is not a timeout issue on the response. (On a side note - does the client call a HEAD before any other request? Perhaps that's too much?) In the previous version of my little service I was using an Elasticsearch client that I wrote. It also uses HttpWebRequest to do its thing. But it works fine under ./service\_user or any other user. Any ideas of what am I missing? Thank you. tjk 🙂 ====== 2015-01-21 21:08:17,443 [5] ERROR - Failed to update index template 'wk-rule' with exception.

Funny story. Before I posted I suspected, my timeout was on the low end. I believe the default is 200 ms. I increased it to 500, then to 2000, without any effect. After the post I did additional experiments and it turned out it was indeed the timeout, with a twist. When running as the local service\_user, the first request takes 13 - 14 seconds. When running as the domain user it takes about 10 - 13 ms. So somehow my local user has issues with DNS or something. The requests are made to [http://MyLocalBox:9200](http://MyLocalBox:9200). If I change that to [http://localhost:9200](http://localhost:9200) the requests for the service\_user work as expected - as fast as any. But even if I use the IP address - the first request is back to 14 seconds. tjk 🙂 -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
