`meteor mongo XXX.meteor.com` giving "exception: login failed" - workaround

This workaround isn’t working for me. I’m still getting the “login failed” exception.

I’m new to Meteor and not sure how to access the deployed website’s MongoDB. I’ve used meteor login to login to meteor before doing the instructions you’ve posted, but to no avail.

Would anyone be able to help? I’ve posted a question on this forum here: Trying to access deployed Meteor website MongoDB Database, getting exception: login failed
