WordPress Multisite Medial Library not working for .online domain

I fixed it. It was the :// issue. Using a sql editor, I saw that the site was pointing to https:///[domain].online. Not sure why changing that in the wordpress admin interface did not fix it, but removing the extra slash in the database fixed it.
