Thanks to Brian Lough and everyone who solved the problem.
I am using esp8266
This problem occurred after using TLS1.2.
I have observed this for over 20 days.
It occurs only at 12:00 to 14:00 GMT.
This time, I checked using only the sketches of the examples.
Arduino Version: 1.8.12
Board Version: 2.6.3
Library Version: 1.1.0
Added 'client.setInsecure ()' to setup.
Here's the decoded exception
Exception 28: LoadProhibited: A load referenced a page mapped with an attribute that does not permit loads
