We have an experiment in which each trail has 6 pictures and 1 audio. Some participants were able to complete the task but some were disrupted starting the main task or in the middle of the experiment. It shows a message like “resources pre-loading, please wait, it takes up to 1 min”. And then the following trial does not load the pictures and the audio. It did not happen for every attempt. Would you please take a look and see why this happens?
It’s possible that the farm was receiving many requests when the issue occurred, and failed to respond to some requests for individual resources. Consolidating your resources in a single zip file makes the experiment send a single request, which is more likely to complete that several individual requests. That solution requires an external hosting solution, either a webserver or, for example, an Amazon S3 bucket
