Laravel Bug in \Request::ip()? Why does it return server ip and not client ip?

Question

Laravel

Found a fat bug when transferring a site from one server to another.
Everywhere it is written that \Request::ip() should return the ip of the client, but this is not so. This came to light when moving to another server, as a result of which all places where there was a check for \Request::ip() stopped working correctly.
And in $_SERVER['HTTP_X_REAL_IP'] the real ip of the client is stored, but for some reason Lara cannot pull it up, but takes, as I understand it, the first $_SERVER['REMOTE_ADDR'] that comes across.
How could this happen in a world-class framework and what to do about it?
In each application to replace the implementation of this function?
