Port 9553 (from Firebase) blocked by webhost, can't find a way to successfully cURL over alternate port - nest-api

Question

I'm using PHP and cURL with the REST api, and even though I can cURL the initial Nest Developer api endpoint, once it redirects to Firebase's url it's over port 9553, which my webhost has blocked (no chance to get opened up either). The connection times out and throws the 'could not connect to host' error.
My code is working fine, I can run it on my local server with no problems.
I'm new at using cURL, what are my options? It seems to me that the problem is the port Firebase is insisting on using. I can cURL a number of different locations, over :80 and :443 without problem, just not Firebase's url. Will I need to run through a proxy in order to access the data?
Or, is this something that might be solved by using Firebase's PHP library? I'm not super interested in using it if I don't have to, cURL would do the job nicely, and I don't know really know how it works.

Answer 1

There is no way to get around the redirects with REST, they point to specific ports and hosts in Nest's cloud.
What is wrong with Firebase's Web Sockets client? It is more performant than REST.

joshguerette,
Is your firewall blocking that port?
You can open the port from your c# code with this:
using Microsoft.TeamFoundation.Common;
private void AddPortToFirewall(int portNumber, string name)
{
INetFwMgr icfMgr = null;
try
{
Type TicfMgr = Type.GetTypeFromProgID("HNetCfg.FwMgr");
icfMgr = (INetFwMgr)Activator.CreateInstance(TicfMgr);
}
catch (Exception ex)
{
Debug.WriteLine("Failed in AddPortToFirewall.Activator " + portNumber.ToString() + " " + name + " " + ex.ToString());
return;
}
try
{
INetFwProfile profile;
INetFwOpenPort portClass;
Type TportClass = Type.GetTypeFromProgID("HNetCfg.FWOpenPort");
portClass = (INetFwOpenPort)Activator.CreateInstance(TportClass);
// Get the current profile
profile = icfMgr.LocalPolicy.CurrentProfile;
// Set firewall enabled
if (!profile.FirewallEnabled)
profile.FirewallEnabled = true;
// Set the port properties
portClass.Scope = NET_FW_SCOPE_.NET_FW_SCOPE_ALL;
portClass.Enabled = true;
portClass.Name = name;
portClass.Port = portNumber;
portClass.Protocol = NET_FW_IP_PROTOCOL_.NET_FW_IP_PROTOCOL_TCP;
// Add the port to the ICF Permissions List
bool portExisted = false;
foreach (INetFwOpenPort p in profile.GloballyOpenPorts)
{
if (p.Port == portNumber && p.Name == name)
{
portExisted = true;
Debug.WriteLine("Windows Firewall inbound list:" + p.Port + " " + p.Name);
break;
}
}
if (!portExisted)
{
profile.GloballyOpenPorts.Add(portClass);
Debug.WriteLine("ServicePort " + portNumber.ToString() + " " + name + " was added into Windows Firewall inbound list.");
}
else
{
Debug.WriteLine("ServicePort " + portNumber.ToString() + " " + name + " has already in Windows Firewall inbound list.");
}
}
catch (Exception ex)
{
Debug.WriteLine("Failed in AddPortToFirewall " + portNumber.ToString() + " " + name + " " + ex.ToString());
}
}
