I'm using the logstash mongodb output plugin to write documents to Azure cosmos DB. I am facing the exact same issue as reported here [Logstash MongoDB Output Plugin - command insert requires authentication](https://discuss.elastic.co/t/logstash-mongodb-output-plugin-command-insert-requires-authentication/268265)  
Here is my configuration

```auto
mongodb {
       collection => "mycollection"
        database => "mydatabase"
        isodate => true
        uri => "mongodb://username:password@cosmos-
account.mongo.cosmos.azure.com:10255/?ssl=true&replicaSet=globaldb"
}

```

This is the error I get

```auto
<Mongo::Auth::Unauthorized: User username is not authorized to access .>

```

Is there some special way that the connection string for cosmos db should be mentioned?  
If I try to access this cosmos db instance using the mongo shell and a python script, it works fine. It only fails from logstash
