Page can't display right now : System Error

[Mheilz]

Hello everyone,

What is the possible reason of this system error that a page cannot be able to display in production authoring but working in live? I will insert the screenshot of the error. Thanks for your help!

@Mheilz Is it with only on page or for list of pages.
Check error.log on first priority for more information, looks like backend code is breaking as it is showing 500 something went wrong page.
This page also comes when site is down due to backend server issue or maintenance work.
