How to fix Cannot accept external Xdebug connection $_SERVER["SERVER_NAME"] is empty error?

Question

PHP

Hello!
I'm using PHPStorm + Open Server but XDebug doesn't work for me.
Error:
Cannot accept external Xdebug connection
$_SERVER["SERVER_NAME"] is empty, it may be caused by web server misconfiguration.
Nginx: add fastcgi parameter to nginx configuration, more
Apache: configure ServerName for current VirtualHost, more
Can you please tell me what could be the problem?

Answer 1

Nginx is not configured.
