When calling phpinfo(), it gives an error: "502 Bad Gateway". What could be the reason?

Question

PHP

Hello!
Set up a storm. Registered the path to the php-interpreter, which was installed along with OpenServer.
I do not start OpenServer, I work with a storm. The interpreter (php 7.1.0) works, but when calling, for example, phpinfo() - it gives an error: "502 Bad Gateway". What is the reason?

Answer 1

apparently there is some library in php.ini that cannot be loaded.
see server logs
