I am not sure what scanner you are using, but the PHP versions on both of your servers are no longer supported since 2017. It would be prudent to upgrade the PHP version on both of your servers to at least PHP 7.3
Using old versions is insecure and could lead to hacks and data breaches. You can see the current supported PHP versions here – https://www.php.net/supported-versions.php
