in reply to Investigating connection reset with LWP to an https site

Have you tried adding the" MIME_Version" header?

Something like this:

$mech->add_header( 'MIME_Version' => '1.0' );

From: http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html
MIME version "1.0" is the default for use in HTTP/1.1.

    No mainstream browser has ever included a MIME-Version header in its requests. Thus no websites are likely to pay any attention to it whatsoever.
