Please try deactivate all plugins and check it again.
If it work, let's enable each plugin to check what's plugin caused this issue.
If it still doesn't work, let's contact with your hosting provider and ask them about this. Because as I can see it's issues from Nginx of the hosting.
I was working without save and it crash. Check the screen please. It relay not the good moment !
