Cannot log in to site after Domain Mapping domain deletion

Referencing your usage guide at

While attempting to update a mapped site’s domain from to, I deleted the custom domain. Now, I’m experiencing a loop where I cannot log in to that site’s admin area. I can log in to other sites on this WPMS environment. And I can view, But when I attempt to log in to or, I can get to the site, but not the WP Admin.

1. What should my Network Domain mapping Options be? Right now, I’ve set them to be:

The domain used for the administration area should be the “domain entered by user.”

The domain used for the login area should be the “domain entered by the user”

2. How can I access the site admin now and update that domain record?

I’ll stop here for now. Thanks in advance.
