Socket Queries in Free Hosting

[Santiago]

Hello,

I'm currently working on a project that requires querying a specific DNS server. Unfortunately, on Free Hosting, I'm encountering an issue where the DNS query process isn't working as expected. Here's the part o my of code I'm that is sending and recieving the socket data:

$socket = fsockopen("udp://$dnsServer", 53, $errno, $errstr, 5);
if (!$socket) {
return "Socket creation failed: $errstr ($errno)";
}
// Send the DNS query to the specified DNS server
if (!fwrite($socket, $packet, strlen($packet))) {
return "Failed to send data";
}
// Receive the response
$response = fread($socket, 512);
if ($response === false) {
return "Failed to receive data";
}

 

I'm consistently receiving a "Failed to receive data" error, indicating that my script is unable to retrieve the data from the socket. Could there be any limitations or restrictions on Free Hosting that could be causing this issue?

I solved by using DNS over HTTPS

Yeah, sockets don’t really work right on free hosting. Looks like you got it working, so that’s good!
