I am sending zip files to an external LMS for delivery to contractors. The same files are being used in our internal LMS with no issue but when the external LMS team tries to upload the files they get a error 404. They are speculating that there is an issue with the CBT launcher. Has anyone experienced this before or have suggestions for a solution? I can't figure out why the CBT would work in our LMS but not theirs when it is the same zip file?
