From somewhere, your program gets the idea that 8080 is a (https?) proxy somewhere along the way. Check that %ENV does not contain the string 8080 anywhere. Maybe it is $ENV{HTTP_PROXY} or $ENV{SSL_PROXY} or $ENV{HTTPS_PROXY} or something like that. It's best to remove (or at least, closely inspect) these environment variables before the Perl script actually launches, so that the SSL libraries have no chance of separately picking them up before you manipulate them from Perl.

Hi, After removing the the environment variables I got something different in the output but still with some errors.

This seems to be my error now:

SOAP::Transport::HTTP::Client::send_receive: HTTP/1.1 401 Unauthorized

Am I doing something wrong?
