Getting a "This page is not redirecting properly" with new network setup

I have had my site for some time. I need to create some new ones and decided to set up WP network. I have followed all the instructions. First, here is my system:
FreeBSD 9.1 on my own server. The domain, movingasfastasican.com is set up as a Virtual on my server and all has worked perfectly for years.

Pretty Links work fine. I followed the network install instructions. I added this to the .htaccess file per the instructions in the network setup.
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
# END WordPress

I updated the wp-config.php

/* Multisite */
define( ‘WP_ALLOW_MULTISITE’, true);
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, true);
define(‘DOMAIN_CURRENT_SITE’, ‘movingasfastasican.com’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

When I try to get to https://movingasfastasican.com, this is the redirected URL:

https://movingasfastasican.com/wp-signup.php?new=movingasfastasican.com

I get a “This page is not redirecting properly” message from Firefox.

This started when I clicked the “login” link at the end of the network setup page. Now calling wp-admin or the base URL causes timeout with the redirect error.
