Can you post 4.conf so your example is runable?

I use differing conf files based on whether I want DEBUG or INFO. These are modeled after the examples:

######################################################################
+#########
#                              Log::Log4perl Conf                     
+        #
######################################################################
+#########
log4perl.rootLogger              = INFO, LOG1, SCREEN
log4perl.appender.SCREEN         = Log::Log4perl::Appender::Screen
log4perl.appender.SCREEN.stderr  = 0
log4perl.appender.SCREEN.layout  = Log::Log4perl::Layout::PatternLayou
+t
log4perl.appender.SCREEN.layout.ConversionPattern = %m %n
log4perl.appender.LOG1           = Log::Log4perl::Appender::File
log4perl.appender.LOG1.filename  = /home/hogan/Documents/hogan/logs/4.
+log4perl.txt
log4perl.appender.LOG1.mode      = append
log4perl.appender.LOG1.layout    = Log::Log4perl::Layout::PatternLayou
+t
log4perl.appender.LOG1.layout.ConversionPattern = %d %p %m %n

is 4.conf, and its partner, 3.conf only differs by a word:

######################################################################
+#########
#                              Log::Log4perl Conf                     
+        #
######################################################################

log4perl.rootLogger              = DEBUG, LOG1, SCREEN
log4perl.appender.SCREEN         = Log::Log4perl::Appender::Screen
log4perl.appender.SCREEN.stderr  = 0
log4perl.appender.SCREEN.layout  = Log::Log4perl::Layout::PatternLayou
+t
log4perl.appender.SCREEN.layout.ConversionPattern = %m %n
log4perl.appender.LOG1           = Log::Log4perl::Appender::File
log4perl.appender.LOG1.filename  = /home/hogan/Documents/hogan/logs/3.
+log4perl.txt
log4perl.appender.LOG1.mode      = append
log4perl.appender.LOG1.layout    = Log::Log4perl::Layout::PatternLayou
+t
log4perl.appender.LOG1.layout.ConversionPattern = %d %p %m %n

Do you have a URL which currently isn't failing?

Yes and no. the url was correct, but I had been using

my $jsonstr = $ua->get( $query )->res->dom;

to fetch the json, and it was unsuccessful for that reason. You use the correct url and fetching query in the newest script you posted.
