Redirect of web setup wizard – varnish

After installing varnish, I am unable to get to Web Setup Wizard. The browser spins for a while and then I end up on https://example.com:81/setup with an error that Chrome interprets as: took too long to respond. ERR_CONNECTION_TIMED_OUT which I think means a redirect loop.

My site is Apache and 100% SSL.

My Apache access_log:

My best guess is that there’s something I’m missing in Varnish config that allows access to the setup wizard but I’m not very familiar with varnish setup.
