Issue with SCORM randomly stopping communicating with LMS (Moodle)
We're having an issue where the SCORM quiz randomly stops communicating with the LMS (Moodle 3.11.3). Issue appears to occur only on the 2nd attempt at the quiz. Quiz is setup in Storyline to allow 2 attempts but in the LMS to allow unlimited attempts.
What we see from Moodle logs is the learner takes the assessment, fails to pass the required grade and so takes it again. Often that's fine and they pass 2nd time. But on occasion the SCORM stops communicating with the LMS although the quiz progresses as normal with no indication to the learner that there's an issue. This could be at the start of the 2nd attempt or part way through. We have logs indicating a learner was progressing through 2nd attempt then score stopped. Learner provided screenshot confirming quiz was completed with a pass.
Have setup a test quiz and can get the same to happen - quiz looks to be running fine but nothing logged in Moodle. However, can only simulate by closing course, refreshing browser and going back in. LMS shows SCORM launch but nothing further even though quiz is being taken.
Anyone encountered this and more importantly have a solution?
Screenshot shows test scenario: on question 6 of 10 yet no scored logged in Moodle (yes, refreshed logs!)
