Nest Rest API Connection Refused

Question

I am trying to set my home to away mode using the REST method. I am trying it with cURL, but I keep getting a "Connection refused after a redirect".

My Code:

$ch = curl_init("https://developer-api.nest.com/structures/$id?auth=$access_token");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); 
curl_setopt($ch, CURLOPT_POSTFIELDS, '{"away":"away"}');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $fp);
curl_setopt($ch, CURLOPT_PUT, true);

echo curl_exec($ch);

The error log (with my id and access code changed):

Any idea why the initial connection would work, but the redirect not?

Answer 1

I found the problem to be my webserver had port 9553 blocked on the outbound side, so firebase was not refusing my connection, it was my firewall the whole time. After opening port 9553, everything worked fine.
