Multisite Login Issue

I know this isn't your responsibility, but I cannot find anyone with any experience to help. So I am hoping you may be able to offer up some advice.

I have two sites in a WP Multisite Install that won't let me log directly into them. I get a message in Safari saying that there are too many redirects? Although, I haven't set any redirects. I also haven't made any changes to the site since Monday and this issue just appeared today.

I can log into my main #1 site in the network and if I try to navigate to the two sites' dashboards, I get a page that looks like all the CSS is missing.

There are actually 5 sites on my network and the other 3 have no issues. All the sites appear to be functioning on the live end as well.

I went through the htaccess file and the wp-config file and verified that they were correct.

The database checks out too OK.

I opened a support ticket with my host and they seem to be clueless as well.

All plugins are up to date.

Any thoughts?
