Question, on breaks. Errors #1006, 1008

[Konstantin-seo]

Periodically, 5-10 times per hour, my script crashes into a fatal error. Here is the log:

• Connection closed abnormally while awaiting message; Code 1006 (ABNORMAL_CLOSE); Reason: "TCP connection closed unexpectedly"
• Connection closed abnormally while awaiting message; Code 1008 (POLICY_VIOLATION); Reason: "Exceeded unanswered PING limit"

How can I rewrite the code so that the script does not fall into a fatal error, but just let's say it sleeps for 30 seconds? or maybe there is another way so that this error does not occur and the script runs forever. I'll attach the code, can you help write the correct workaround for this error?

I will be very grateful!

MyCode:

<?php

//require_once ...

use Amp\ByteStream\StreamException;
use Amp\Loop;
use Amp\Websocket;
use Amp\Websocket\Client;
use Amp\Websocket\Client\Connection;
use Amp\Websocket\Client\Handshake;
use Amp\Websocket\ClosedException;
use Amp\Websocket\Message;
use Amp\Websocket\Options;
use Amp\Delayed;
use function Amp\Websocket\Client\connect;
	
	Amp\Loop::run(function () {
	
	$handshake = (new Handshake('wss://mg-s1.site.ru/api/bot/v1/ws?events=message_new'))->withHeader('x-bot-token', '0000000000000000000000000000000000000000000000000');

    $connection = yield connect($handshake);
    yield $connection->send('Hello!');

    try {
		while ($message = yield $connection->receive()) {
			$payload = yield $message->buffer();
			
			$result = json_decode($payload, true);
			
			//handler code

		} 
	} catch (ClosedException $e) {
            logFileEvent ('Connection break. sleep 30 sec');
			logFile ('Errors: ' . $e->getMessage());
			sleep(30);
		} catch (AssertionError $e) {
            logFile ('Errors: ' . $e->getMessage());
            $connection->close();
        } catch (Error $e) {
			logFile ('Errors: ' . $e->getMessage());
            $connection->close();
        } catch (StreamException $e) {
			logFile ('StreamException: ' . $e->getMessage());
            $connection->close();
        }
});

Can you explain why these 2 errors occur and where should I dig to avoid them?

For example, error 1006 occurs for me more than 100 times a day. For some reason, I immediately raise a new connection, but I want to understand the reason for their appearance. Is it my server? library settings?

What options need to be changed heartbeat?
