Are you tired of encountering errors and failures while deploying your Node.js application in cPanel? You’re not alone! Many developers face this frustrating issue, but don’t worry, we’re here to guide you through the troubleshooting process and get your application up and running in no time.
What’s Causing the Failure?
- Incorrect Node.js version
- Incompatible dependencies
- Incorrect file permissions
- Missing dependencies
- Incorrect configuration files
- Outdated cPanel version
Prerequisites
Before we begin, ensure you have the following:
- Node.js installed on your cPanel account
- A compatible version of Node.js (at least 14.17.0)
- A cPanel account with SSH access
- A basic understanding of Node.js and cPanel
Step-by-Step Troubleshooting Guide
Follow these steps to identify and fix the issues preventing your Node.js application from deploying successfully:
Step 1: Verify Node.js Version
Ensure you’re using a compatible version of Node.js. You can check the version by running the following command in your SSH terminal:
node -vIf you’re using an outdated version, update Node.js to the latest version:
nvm install nodeor
nvm use nodeStep 2: Check Dependencies
Verify that all dependencies are installed and compatible. Run the following command to install dependencies:
npm installIf you encounter any issues, try cleaning the cache and reinstalling dependencies:
npm cache clean --forcenpm installStep 3: Fix File Permissions
Ensure that your application files have the correct permissions. You can set the permissions using the following command:
chmod -R 755 /path/to/your/applicationReplace /path/to/your/application with the actual path to your application.
Step 4: Check Configuration Files
Verify that your configuration files are correct and properly configured. Check your:
package.jsonfile for correct dependencies and scriptsapp.jsorserver.jsfile for correct server configurationenvironmentVariablesfile for correct environment variables
Step 5: Check cPanel Version
Ensure you’re running the latest version of cPanel. You can check the version by logging into your cPanel account and looking for the version number in the top right corner.
If you’re using an outdated version, contact your hosting provider to update cPanel.
Common Deployment Errors and Fixes
Here are some common deployment errors and their fixes:
| Error | Fix |
|---|---|
| ENOSPC: System limit for number of file watchers reached | increase the fs.inotify.max_user_watches limit by running echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p |
| npm ERR! code ECONNREFUSED | check your internet connection, or try running npm config set registry https://registry.npmjs.org/ |
| Failed to load resource: net::ERR_CONNECTION_REFUSED | check your application’s server configuration, or try running npm run start to restart the server |
Conclusion
By following these steps and troubleshooting guides, you should be able to identify and fix the issues preventing your Node.js application from deploying successfully in cPanel. Remember to stay calm, be patient, and don’t hesitate to seek help if you’re stuck.

Frequently Asked Questions
Deploying a Node.js application on cPanel can be a breeze, but sometimes, it’s not all sunshine and rainbows. Check out these FAQs to troubleshoot common issues and get your app up and running in no time!
Why does my Node.js application fail to deploy on cPanel?
Usually, this happens when the Node.js version on your cPanel doesn’t match the version required by your application. Make sure to check the version compatibility and update your cPanel’s Node.js version accordingly. Additionally, ensure that the necessary dependencies are installed and configured correctly.
What’s causing the “Cannot find module” error during deployment?
This error typically occurs when your application is trying to load a module that’s not installed or not properly configured. Double-check your package.json file to ensure all dependencies are listed and installed correctly. You can try running npm install or yarn install to reinstall the dependencies.
Why is my application not listening on the correct port?
By default, cPanel assigns a random available port to your Node.js application. To specify a custom port, you need to configure your application to listen on that port. Update your code to use the correct port number, and also ensure that the port is not already in use by another process.
How do I troubleshoot issues with my application’s environment variables?
To troubleshoot environment variable issues, check if the variables are properly set in your cPanel’s environment variables section. Verify that the variables are correctly configured in your application’s code, and that they’re being used correctly. You can also try logging the environment variables to debug the issue.
Why does my application crash or timeout during deployment?
This could be due to resource limitations, such as insufficient memory or CPU. Check your cPanel’s resource usage and adjust the resource allocation accordingly. You can also try optimizing your application’s performance by reducing memory usage, implementing caching, or using a load balancer.
