How can I connect MongoDB to NoSQLBooster

I am trying to connect to MongoDB using NoSQLBooster. I have the credentials and the server name. I am not the admin of MongoDB. This server is on the network of my organization. I have been working to connect to MongoDB for weeks using the internet search, but nothing didn’t work. Any suggestions?

MongoNetworkError: failed to connect to server [servername:27017] on first connect [Error: connect ECONNREFUSED ServerIP:27017
