Hello Elastic Users,

I am trying to check if my Elasticsearch is working fine or not by running the following command in WindowsPowershell.

Invoke-RestMethod [http://localhost:9200](http://localhost:9200)

But it threw an 401-Authentication error. I am not sure how to pass on the credentials along with Invoke Command in Powershell.

\<  
PS C:\Users\hussshe\> Invoke-RestMethod [http://localhost:9200](http://localhost:9200)  
Invoke-RestMethod : {"error":{"root\_cause":[{"type":"security\_exception","reason":"missing authentication credentials  
for REST request [/]","header":{"WWW-Authenticate":"Basic realm="security"  
charset="UTF-8""}}],"type":"security\_exception","reason":"missing authentication credentials for REST request  
[/]","header":{"WWW-Authenticate":"Basic realm="security" charset="UTF-8""}},"status":401}  
At line:1 char:1

- Invoke-RestMethod [http://localhost:9200](http://localhost:9200)
- 

```auto
  + CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebExc
 eption
  + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

```

P.S: I am a beginner trying to learn ELK on my own.

Any help would be appreciated.

I don't know powershell, but a quick web search shows me this doesn't look easy - [https://www.reddit.com/r/PowerShell/comments/gs7i4s/calling\_an\_api\_using\_invokerestmethod\_using/](https://www.reddit.com/r/PowerShell/comments/gs7i4s/calling_an_api_using_invokerestmethod_using/)

Unfortunately this is outside the scope of what we can assist with here sorry to say.
