On my Multi use site I am getting to many redirects!

On my RuppertMarketing.com Multi use site if I try to log into any of my Sub sites I get:
The ruppertmarketing.com page isn’t working

ruppertmarketing.com redirected you too many times.

ERR_TOO_MANY_REDIRECTS
This is the URL I am trying to access:
https://ruppertmarketing.com/montanaspraypainter/wp-admin/
I have disabled all my plugins and got the same response. So I disabled my .htaccess file still nothing, the only thing I added before all this happened was rekeying my ssl certificate and I added gtmetrix plugin as well as w3 total cache but have since deleted both. Please help I am at a loss of what it could be!
