OpenSpinkler server sends back RST using HTTP::Tiny

[jdent]

Using OpenSprinkler Pi, App 1.4.5, firmware 2.1.5(1)

I’m trying to make API calls using Perl running on my pi and HTTP::Tiny (included in Raspbian). 9+ times out of 10, when I run the program, the GET request returns:

Could not read from socket: ‘Connection reset by peer’ at /usr/share/perl/5.14/HTTP/Tiny.pm line 162

Doing a packet trace, I see that OpenSprinkler is sending the response data back, but instead of closing the connection normally, it sends back an RST. Curl for the exact same URL always works and I see the connection being properly closed. The test program is very simple, so hopefully the problem can be easily duplicated:

#!/usr/bin/perl

use JSON::PP;
use HTTP::Tiny;
use strict;
require "dumpvar.pl";

my ($response, $decodedResult, $json, $url, $http);

$url = 'http://127.0.0.1:8080/jc?pw=hashedpasswordhere';
$http = HTTP::Tiny->new(
                'proxy' => undef,
                 );
$response = $http->get($url);

dumpValue ($response);

if (!$response->{success}) {
        print STDERR "Request failed: " . $response->{content} . "\n";
        exit 1;
        }

$json = JSON::PP->new->ascii->pretty->allow_nonref;
$decodedResult = $json->decode( $response->{content} );

dumpValue ($decodedResult);
