I followed all the steps and got error ‘connection refused’

connecting to: mongodb://localhost:27000/admin?gssapiServiceName=mongodb

Hi @Hadeel_Al-khalailah,

Welcome to the MongoDB Community Forums,

Can you kindly share the screenshot of the IDE with the command you entered along with the error message you got!!

Thanks,
