PHP Warning: file_get_contents(http://localhost:8080/assets/mail/template.html): failed to open stream: HTTP request failed!

[lucasdgimenez]

I'm working on a project built with php slim, where I have a registration screen that when clicking on register triggers the /register route of the parent route "/clients"



This is the error:

PHP Warning: file_get_contents(http://localhost:8080/assets/mail/template.html): failed to open stream: HTTP request failed!

$templateMail = file_get_contents(self::$templateMail);

$message = str_replace('HTMLMessage', $message, $templateMail);

This is the line where the error occurs

The complete file is called Email.php

I've already tried to google this problem and most indicate curl's solution instead of file_get_contents, the problem is that when trying to implement this curl solution (which is commented in the code above) the system runs an infinite loading, I don't know exactly which one that could be the problem.

The php version is 7.4 and the apache version is 2.4.52
