Looks like there is an issue with the URI in your config file. Should be either `http://kibana.onoff.ge:9200` or `https://kibana.onoff.ge:9200`.

it should be https, but when `i am trying [https://kibana.onoff.ge:9200](https://kibana.onoff.ge:9200) this uri besides this kibana.onoff.ge:9200 this gives me this error as original exeption.{"Failed to ping the specified node.. Call: Status code unknown from: HEAD /"}

What version of the client are you using e.g. NEST 7.3.0?

Can you make a HEAD request to `https://kibana.onoff.ge:9200` outside of the client, on the same machine? For example, with PowerShell

```ps
$user = "ID"
$password = "PWD" | ConvertTo-SecureString -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential ($user , $password)

Invoke-WebRequest "https://kibana.onoff.ge:9200" -Method Head -Credential $credential `
    -UseBasicParsing -ContentType "application/json"

```
