Yes, your /checkout/onepage/ returns error 500. You need to check your logs to see why.
It can be because you changed the host. There are many reasons for the HTTP error 500, some of which can be because of your browser cache issues, server database problem or corrupted database, PHP timeout or error, or theme or plugin issue.
For an ecommerce Magento site the best option is to go for a Managed Magento Hosting. It not only take care of your server technicalities but also speeds up your website and make its performance more optimized and reliable.
Have you tried clearing the caches?
You will find all your log files in the /var/log/ folder.
Tail those logs and look into what happens when you get to the checkout page. I would expect some sort of exception in the logs to appear due to the 500 error, and that exception will tell you where the problem is.
