I have a course that was built in Storyline 2.11 and worked fine. Today I re-published the course in Storyline 360. I tested it on local drive - it worked fine. I tested it in my LMS - got the 'Error - unable to acquire LMS API...' error (tried both IE and Firefox). In Firefox I could see the table of contents and but no course and the error. In IE it was just a whirling icon with the error.
Then I tested it in Scorm Cloud and it passed.
Any ideas why it would fail the LMS test but pass in the Cloud? The content is almost the same as it was for Storyline 2.11.
