PWA Studio: Browser displays “Cannot proxy to“ error

This topic discusses a solution when your web browser displays a "Cannot proxy to" and the console displays an ENOTFOUND error when using Magento Progressive Web App (PWA) Studio.

Affected products and versions

• Magento PWA Studio

Issue

Step to reproduce

• Load your Magento store in a browser.

Expected result

• The Magento store loads normally in your browser.

Actual result

• Your web browser displays the “Cannot proxy to“ error and the console displays an ENOTFOUND error.

Cause

NodeJS cannot resolve the hostname of your Magento store.

Solution

1. Make sure your Magento store loads in more than one web browser.
2. If you are running a local DNS server or VPN, add an entry to your hostfile (located in /etc/hosts) and manually map this domain (Generic instructions on hostfile editing) so NodeJS can resolve it.
