I've been fooled again, HTTP 599 Network Connect Timeout Error (Microsoft),https://httpstatuses.com/599.

Thanks this is the info that I was after. I am however a bit confused since I thought that HTTP::Tiny is part of the core perl distribution. I'm using 5.14.2 . So it ships without all the dependant modules ?

https support is not in the Perl core.

Don't worry! HTTP::Tiny will rot bits as webmasters implement HTTPS Everywhere! except for the backlash of hip retro unencrypted sites! Then one day HTTP::Tiny, after years of recommendations followed by years of disillusionment [YOU ARE HERE] followed by years of disparagement, will be unceremoniously deprecated and REMOVED FROM THE PERL CORE!

If it could happen to CGI, it will probably happen to HTTP::Tiny 🔋🗑

UNLESS someone rescues HTTP::Tiny to evolve some sort of fallback functionality along the lines of HTTP::Any like this silly core one-liner, when fed an https url on an https-less perl, will fail and fallback on a random selection of wget or curl (or, like, all known https clients on every operating system?):

perl -MIPC::Cmd=can_run,run -MHTTP::Tiny -le'@c=({wget=>"wget -O-"},{c
+url=>"curl"});$u=shift;$r=HTTP::Tiny->new->get($u);if($r->{status}==5
+99){($a,$b)=%{$c[rand@c]};if(my $cmd=can_run($a)){if(scalar run(comma
+nd=>"$b $u",buffer=>\my $data)){print"$data\n$cmd"}}}else{print"$r->{
+content}\ntiny"}' "https://www.perlmonks.org"

perl 
-MIPC::Cmd=can_run,run 
-MHTTP::Tiny 
-le'
@c=({wget=>"wget -O-"},{curl=>"curl"});
$u=shift;
$r=HTTP::Tiny->new->get($u);
if($r->{status}==599){
 ($a,$b)=%{$c[rand@c]};
 if(my $cmd=can_run($a)){
  if(scalar run(command=>"$b $u",buffer=>\my $data){
   print"$data\n$cmd"
  }
 }
}
else{print"$r->{content}\ntiny"}'

Let's fix it!

The reason that HTTP::Tiny is in core is as a fallback for CPAN to use when wget or curl don't work. So there is no need to "fix" this.
