Installing and upgrading help

The public IP address of my server is:  104.131.35.160

This is my server at Cloudways, and this is where my moodle site has been working for the past 3 years.  

When you enter this IP address in the URL bar, it takes you to my moodle site and the URL bar changes to display http://moodle-1840-18409-42718.cloudwaysapps.com/.

But, in the past, it has redirected from this page to the login page for my website.  

Now, however, it just redirects back to this same page.
