Trying to set up MongoDB for my Node.JS application. I running this command:

*** It looks like this is a MongoDB Atlas cluster. Please ensure that your IP whitelist allows connections from your network.

I have whitelisted my IP address and made sure everything is in order. What could be causing this problem and how could I fix it? Why would this problem be occurring?

回答1:

So you have to take care of 2 things.

1) First off, having mongodb in your $PATH, create a .bash_profile under the home folder if you don't have it already, then insert the following.(For Ubuntu)

export PATH="$PATH:/usr/bin/mongo" Make sure you place the location of mongo on your computer. If you don't know the location, type whereis mongo on the terminal. After saving, type source ~/.bashrc in the terminal.

2) Lastly, copy the connect link from the mongodb atlas, and when asked for username and password

please provide the credentials set to access the database not the mongdb atlas account.

回答2:

Create a simple password which doesn't have any special characters, it only includes alphabets and numbers.

I wasn't able to access but changing password worked for me.

回答3:

I realise that "just wait a bit" isn't a terribly constructive answer, but I had the same issue and no luck in finding a solution, so left it for a couple hours and came back to find it working perfectly.

The text that says your change has been deployed is misleading. Not sure why it takes several hours to kick in, but for reference I found this when using the M0 Sandbox cluster tier.
