I upgraded the monog version to 4.2 to be insync with mongo version in atlas, didnt solve the problem getting this error mongo

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

Hoping to get a resolution from the experts. Thanks in Advance :)

Solution

  • First, in Atlas:

    1. Ensure the cluster itself looks healthy in "Clusters"
    2. Go to "Network Access" and ensure your IP is allowed
    3. Just to be safe, go to "Database Access" and create a new user with proper permissions

    If your problem is similar to Cannot connect to mongodb atlas through mongo shell, it might be that your IP changed or something, and you need to allow your current IP.
