cannot access my wp-admin

It would seem that when I log into the hub and click the WP ADMIN button I get a message that says 'Server Error

Whoops, something went wrong at our end!

Please try again later or contact us if the problem persists.'

This has been going on since about 10 or 11pm Central Time and still continues. I have tried typing the address https://newt.wpmudev.host and https://newt.wpmudev.host/wp-admin in chrome, firefox, and exploirer and still not getting access to my site.
