Caddy Server, http.fastcgi 502 Error - php

Question

My Caddy File
http://bot.vibs.tech {
root /home/caddy/www/botsite
tls off
errors {
404 /home/caddy/www/botsite/404.html
}
fastcgi / 127.0.0.1:9001 php {
ext .php
split .php
index index.php
}
}
The Webpage http://bot.vibs.tech/test.php
Home Page http://bot.vibs.tech
My PHP Script
<?php
if($_POST["submit"]) {
$test=$_POST["botsname"];
$redis->set(';message';, $test;);
$value = $redis->get('message');
<p>$value</p>
}
if (empty($url)) {
echo "<h2><div style=\"color: Black;\">THANK YOU, YOUR BOT IS BEING MADE!</div></h2>";
echo "<h2><div style=\color: Black;\"><a href=http://bot.vibs.tech/>HOME</a></div></h2>";
}
Tried lots of different things, not sure what else i could try to do.
Also im trying to implement Redis to this so i can have a database from a form im currently working on.

tried /etc/init.d/php7.0-fpm status
