Why do I receive the error "Error: Download failed. Check the network connection and retry." when installing using the MATLAB Package Manager?

When trying to install MathWorks products with the MATLAB Package Manager (MPM), I encounter an error like the following:

Error: Download failed. Check the network connection and retry.
How do I resolve this?

If your network filters traffic through a proxy server to restrict internet access, you might encounter this error. To prevent this error, pass your network’s proxy server information to mpm by using the HTTP_PROXY and HTTPS_PROXY environment variables. Please see the following article for more information:

Does the MATLAB Package Manager support proxy servers?
