ArangoDB-NET Error: System.Net.WebException: 'No such host is known No such host is known'

I'm working on a project that needed a Graph DB. I'm developing the project using C# .Net Core. I had to choose ArangoDB as a Graph DB for this project. Unfortunately, there is no official driver for .Net. That's why I choose a community driver. That is ArangoDB-NET.

https://www.nuget.org/packages/ArangoDB-NET/

https://github.com/yojimbo87/ArangoDB-NET

The driver is working fine with my local installed ArangoDB database. The driver is returning an error when I'm trying to deploy the database in ArangoDB Cloud (ArangoDB Oasis).

Error: System.Net.WebException: 'No such host is known No such host is known'

enter image description here

Please check the below information about the database connection:

Connection String Settings:

  "DatabaseSettings": {
    "ConnectionName": "CloudDBConnection",
    "Host": "https://xxxxxxxx.arangodb.cloud",
    "Port": 8529,
    "UserName": "root",
    "Password": "xxxxxxxx",
    "DatabaseName": "KKBDTestDB"
  }

Database Connection:

private readonly ADatabase db;
public DatabseService(IDatabaseSettings settings)
{
    ASettings.AddConnection(settings.ConnectionName, settings.Host, settings.Port, false, settings.DatabaseName, settings.UserName, settings.Password, true);
    db = new ADatabase(settings.ConnectionName);
}

1) Remove https from your host name, then try.

Connection string should be:

"DatabaseSettings": {
    "ConnectionName": "CloudDBConnection",
    "Host": "xxxxxxxx.arangodb.cloud",
    "Port": 8529,
    "UserName": "root",
    "Password": "xxxxxxxx",
    "DatabaseName": "KKBDTestDB"
  }

2) Download public key for windows from arongodb cloud and follow the following steps:

  1. Convert Certificate (PEM) to ca-9676da18.crt
  2. Open a Powershell with Run as Administrator
  3. certutil -addstore root ca-9676da18.crt
