So if you navigate to (replace MOODLE-2 with your Moodle 2 domain name): https://MOODLE-2/admin/settings.php?section=enrolsettingslti_registrations
There is no row listing for Moodle 1 as a registered platform.
If I'm understanding you, I'd turn debug massages up to DEVELOPER on Moodle 2 (/admin/settings.php?section=debugging) and go through the steps of "In Moodle (for Moodle-to-Moodle LTI):" again. Dynamic registration is a really impressive piece of technology that Moodle-to-Moodle allows, so my guess is there's a network blockage between the two servers or something that you should see in an error when carefully stepping through those five instructions.
