Probably this? https://stackoverflow.com/questions/55695565/error-message-mongoerror-bad-auth-authentication-failed-through-uri-string

Essentially, your connection url is probably wrong

@MR.Robot that connection string is secret, don’t post it here. I removed the message. Are you absolutely sure it doesn’t have any mistakes mentioned in the link above?

Can you query the database with [mongodb compass](https://www.mongodb.com/products/tools/compass)? If the connection string is correct, it should work there, if not you need to fix your connection string first

I'm querying with mongoose.

Yes I know. But I want to ensure that the connection string is correct. Download compass and use it to inspect the database with a connection string, does it work?

I'm connected with compass

but I could not connect in my own project
