EasyApache interface is not working

Symptoms

When attempting to access the EasyApache 4 interface, the page is empty, or the configure button redirects back to the main page.

Cause

This occurs when a script error prevents the page elements from loading. Using the browser tools, one of the following script errors can be found. In the example below, we can see the debug value is present in the element.

EasyApache4:1 Refused to execute script from 'https://203.0.113.2:2087/cpsess123456789/scripts7/EasyApache4/lz-string.js?debug=1' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.Understand this error

lz-string.js?debug=1:1 Uncaught SyntaxError: Unexpected token '<' (at lz-string.js?debug=1:1:1) 
Error storing localStorage item ea4RawPkgList: TypeError: Cannot read properties of undefined (reading 'compress')

We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-51067. Follow this article to receive an email notification when a solution is published in the product.
