We have an Adapt Authoring tool server (0.8.1/2.4.0) which have had some performance issues (described in another thread).
But as I tried to export the course, the export just stops after a while.
When I look in the export folder on the server there is a zip-file that seems to be a correct export file but the AT does not download it.
I get this in the Chrome console:
Uncaught TypeError: Cannot read property 'message' of undefined

at XMLHttpRequest.t (origin.js?20190628095404773:213)
Failed to load resource: net::ERR_EMPTY_RESPONSE
I have also attached a file with the output in the server console.
