perform load testing normally before, but one day it suddenly reported a Socket Exception error

Expected behavior

perform correctly

Actual behavior

I was able to use Jmeter to perform load testing normally before, but one day it suddenly reported a Socket Exception error during execution. This is the error message.

Sample Result:

Doesn't that imply that the server might be struggling to handle the load?
