Unable to load questions on course:504 Gateway Time-out
The exercises in my course are not loading. Instead, the message that appears is 504 Gateway Time-out. I've tried using different browsers but the same happens. This is the first time this is happening.
The course has run for 2 years with no issues. I have not made any changes to the settings. Appreciate your prompt assistance as the course is running now and students are facing problems completing the course.
