That's Mailman core trying to talk to HyperKitty over http to get the list archives URL. The URL it's trying to reach is set in the "deployment/mailman-hyperkitty.cfg". My guess is that you need to update it because if HyperKitty is running under Apache, the port is no longer 8000, it's 80 (so you can remove it from the URL). If that's the problem, I'll update the README file.
