Need help : Client creation fails with Json Exception

[Ankzz]

Tried with two versions of 'azure-documentdb' library : 2.4.7 and 2.3.0 . Same error.

When I am trying to create a client object of type DocumentClient , I receive following error:
HTTP/1.1 404 Not Found for the initial request to read information from the Cosmos-Db.

Code used is as simple as:

docClient = new DocumentClient("https://xxx.mongo.cosmos.azure.com:443/", "<primary-key>", null /* Providing a policy also did made no difference */ , ConsistencyLevel.Session);

Following error is received:
