Solving MongoDB Atlas Database Connection Failures<\/h2>\n

\"Database<\/a><\/p>\n

This error usually occurs because of network access restrictions in MongoDB and firewall restrictions on the application server.<\/p>\n

To fix it, you need to add the server’s IP address where your application is running to the allowed list in your MongoDB Atlas account.<\/p>\n

Here\u2019s how to whitelist your application server’s IP address in MongoDB Atlas:<\/p>\n

Step 1.<\/strong> Log in to your MongoDB Atlas account.<\/p>\n

Step 2.<\/strong> Select your project from the Projects list and click on it (e.g., Nodejs-test-project).<\/p>\n

\"Select<\/a><\/p>\n

Step 3.<\/strong> Click on “Network Access”<\/strong> under the Security tab on the left.<\/p>\n

\"Network<\/a><\/p>\n

Step 4.<\/strong> In the Network Access window, click on “IP Access List”<\/strong> to see the list of whitelisted IP addresses. Click “Add IP address”<\/strong> to add a new one.<\/p>\n

\"Add<\/a><\/p>\n

Step 5.<\/strong> In the Access list entry field, enter your application server’s IP address (e.g., 192.168.2.155\/32).<\/p>\n

Step 6.<\/strong> Add a note in the Comment field to identify the IP address easily. Click “Confirm”<\/strong> to add it to MongoDB Network Access.<\/p>\n

\"Confirm\"<\/a><\/p>\n

Step 7.<\/strong> Once added, the IP address will appear in the IP Address List.<\/p>\n

\"IP<\/a><\/p>\n

Congratulations! Your application server’s IP address is now whitelisted in MongoDB Atlas. You can use the same steps to whitelist your local system’s IP address.<\/p>\n

Next, you need to allow the port number used by your application in the software firewall<\/a> on your AccuWeb.Cloud account. Here\u2019s how to do it:<\/p>\n

Step 1.<\/strong> Log in to your AccuWeb.Cloud dashboard.<\/p>\n

Step 2.<\/strong> Choose the environment where you want to allow the port (e.g., mynodejsapp).<\/p>\n

Step 3.<\/strong> Click on the Settings<\/strong> icon.<\/p>\n

\"Settings\"<\/a><\/p>\n

Step 4. <\/strong>In the Settings window, select the Firewall<\/strong> option.<\/p>\n

\"Firewall<\/a><\/p>\n

Step 5.<\/strong> In the Firewall window, click on “Inbound Rules,”<\/strong> then click the “Add”<\/strong> button.<\/p>\n

\"Click<\/a><\/p>\n

Step 6.<\/strong> In the Add Inbound Rule<\/a> window, fill in the following details:<\/p>\n
