Script runs twice

[juljan555]

The below script on a server with PHP-FPM and PHP 8 runs twice. Second time exactly after 1 minute. Stack with Nginx in front and Apache in the back. Already set timeout exec and input to 1 hour.
*******************************
<?php

/*
* The purpose of this script is to see if cron jobs running more than 1 minute
* recall themselves

You can add a message by using &note=ThisUsingCronMessage

call like: https://wdleadscalls.org/cronjobs/testm ... NoteForYou

*/

//Did they add a note
if (isset($_GET['note'])){
$note = $_GET['note'];
}else{
$note = "";
}



$Now = date('Y-m-d H:i:s');
echo "<h2> Starting This At $Now (Note:$note)</h2>";
$fp = fopen('LOGtestmultical2.txt', 'a');//opens file in append mode.
$Now = date('Y-m-d H:i:s');
$Msg = "\n Program Launched At: $Now";
fwrite($fp, $Msg);

fclose($fp);

$StartNow = $Now;

//Sleep for 4 minutes
sleep(241);


$fp = fopen('LOGtestmultical2.txt', 'a');//opens file in append mode.
$Now = date('Y-m-d H:i:s');
$Msg = "\n Program Finished At: $Now Started At:($StartNow) (Note:$note)";
fwrite($fp, $Msg);

fclose($fp);


$Now = date('Y-m-d H:i:s');
echo "<h2> FINISHING This At $Now Started At:($StartNow) (Note:$note)</h2>";

Any idea why? Where should I look?

"Stack with Nginx in front and Apache in the back"
what does it mean?

It looks like the issue is somewhere else
