Why can't I catch events from the Asterisk AMI through PHP?

Question

PHP

My task is to catch incoming calls using Asterisk and PHP. I tried to do everything according to this article https://habr.com/en/post/311986/, but in the end it gives an error:
"Exception raised: Failed to listen on "tcp://192.168.0.241:8080": Cannot assign requested address
File: path/vendor/react/socket/src/TcpServer.php Line: 164"
I have a testast directory, it contains php file v1_ast and 4 php classes:
PAMI and Ratchet were installed through Composer:
Here is the v1_ast file itself. php:
4 classes were copied from the article I mentioned at the beginning. I changed the host, password and login in the AsteriskDaemon class, and also in each class I wrote require '../vendor/autoload.php';to make these classes use the packages installed by Composer

Where did you get the address 192.168.0.241 from? Just copied and pasted?
