You're seeing this message because something's preventing Flocabulary from loading correctly.
Try the following steps below to troubleshoot the problem. If you try each, and are still having issues, please shoot us an email at info@flocabulary.com.
1. Do you have any firewalls or security policies in place that may be affecting usage?
- It is possible that your school's firewall is blocking the site where we host our images and media, basically rendering our site as raw HTML. If that is the problem, you should be able to solve it by asking your tech team to unblock flocabulary.com and flocabulary.s3.amazonaws.com (or add it as a "safe site").
2. Does your school or district have sufficient bandwidth to stream media in general (e.g. YouTube)?
- Is there any change in behavior between peak and non-peak hours?
- A good test to see if it's a network issue: Grab a video file such as https://flocabulary.s3.amazonaws.com/media-jrev/test-video.mp4 and see how long it takes to establish connection and download.
3. Does your school or district use any network management / optimization tools (software or appliances) that could be limiting bandwidth in any of the following ways:
- File extension or MIME type. (Our video content files are MP4; audio are MP3.)
- File size. (Our video files are ~20MB; audio are ~4MB.)
- Limited allocation per user or device
- Prioritizing / deprioritizing traffic from certain domains
