We are unable to regrade wiris quizzes.
This is the initial error and stack trace:
Sorry! The system can not generate one of the questions of the quiz. Maybe there is a temporary connection problem right now. Maybe the question algorithm has a bug, and fails sometimes. Maybe it will fail always. Don't panic... You can retry the quiz, without penalty, just clicking Continue. You can also tell the Teachers that there is an issue with the question titled: 'Normal distribution 1'

If I comment out the try and catch block in the function 'call_wiris_service' then the stack trace is:
Exception - Remote exception: java.io.IOException: Connexion error while connecting with wiris kernel: Connection reset
