Cause 1: Lack of system resources

Jupyter Notebook requires a certain amount of system resources, including memory and CPU power, to run smoothly. If your system is running low on resources, it can lead to a 500 Internal Server Error. It means the notebook requires more energy.

Cause 2: Conflicting dependencies

Jupyter Notebook relies on several dependencies to function properly. If there are conflicts between these dependencies or if they are not installed correctly, it can result in an internal server error.

Cause 3: Configuration issues

Wrong configuration settings in Jupyter Notebook can also trigger this error. It could be related to the server settings, authentication, or other configuration parameters.

Now let’s know how to solve this issues

Solution 1: Restart the Jupyter Notebook Server

Sometimes, the error could be temporary and can be resolved by simply restarting the Jupyter Notebook server. To do this, you can either close the notebook and reopen it or stop the server from the command line and start it again. This simple step can often fix the internal server error.

Solution 2: Verify System Resources

As mentioned earlier, insufficient system resources can cause the 500 Internal Server Error. To overcome this, you can close any unnecessary applications or processes running in the background to free up system memory and CPU power. Additionally, consider upgrading your hardware to avoid errors due to resource limitations.

Solution 3: Update Dependencies

Updating the dependencies used by Jupyter Notebook can help resolve conflicts and ensure smooth execution. You can use package managers like Conda or Pip to update the dependencies. It’s also a good practice to create a virtual environment for Jupyter Notebook to avoid conflicts with other Python packages installed on your system.

Solution 4: Verify Configuration Settings

Incorrect configuration settings can lead to internal server errors. Double-check the configuration files of Jupyter Notebook to ensure they are set up correctly. Pay special attention to server settings, authentication mechanisms, and firewall configurations. If necessary, consult the Jupyter Notebook documentation or seek help from the community to troubleshoot specific configuration issues.

Solution 5: Reinstall Jupyter Notebook

If all the above solutions do not work, you can try reinstalling Jupyter Notebook. Uninstall it completely from your system and then reinstall the latest version. This can often fix any underlying issues causing the 500 Internal Server Error.


In most cases, the coders get 500 internal server errors in Jupyter Notebook due to resource limitations. If you are getting the error then you should upgrade the hardware. It not only solves the error but also makes you more productive. Always keep the Jupyter Notebook and its dependencies to avoid the error.
