Most Rise 360 SCORM packages showing blank screen or “502 Bad Gateway” in LMS

Hi everyone — I’m running into a serious issue and hoping to gather some insights from others who might be experiencing the same thing.

Course details:

• Created in Rise 360 and exported as SCORM packages (SCORM 1.2 format)
• Uploaded to our LMS (Coassemble) — all courses have been live and working normally for months

Issue now:

• When launching, most courses display a blank screen or a “502 Bad Gateway (nginx)” error.
• We’ve tested about 50 Rise 360 courses, and only 2 of them are currently loading properly.
• The same SCORM files show identical errors when tested in SCORM Cloud, so it doesn’t appear to be LMS-specific.

What we’ve already verified:

• The LMS itself is operational — but nearly all Rise 360 courses are failing to load.
• None of the courses were recently edited, re-exported, or changed in any way.
• The issue began suddenly within the last couple of days.

Our suspicion:

• These SCORM exports may be referencing external resources (such as Articulate-hosted scripts, fonts, or media) that are currently unavailable.

Questions:

1. Is anyone else experiencing this same issue with Rise 360 courses (blank screens or “502 Bad Gateway” errors) in their LMS or in SCORM Cloud?
2. We’re trying to troubleshoot what might be causing it, but our LMS provider hasn’t been very helpful — so we’d appreciate hearing from anyone who has seen something similar.
3. Has anyone identified specific Rise 360 export settings or dependencies that could lead to this issue if external resources become unavailable?

Thanks in advance for any help or insight you can share — this issue is affecting a large portion of our live e-learning content, so any shared experiences or fixes would be greatly appreciated!
