Collaborate troubleshooting

If you encounter an issue when using Blackboard Collaborate please follow our troubleshooting guide. If the issue is resolved by following the suggestions throughout the guide, then please don’t submit the form. If your issue is not resolved after running through the troubleshooting guide, complete all information requested, submit the form and a ticket will be sent to Help4U to allow the CTIL team to investigate.

Please don’t complete the troubleshooting guide on behalf on someone else (or a class of students), you should encourage each user encountering an issue with Collaborate to run through the troubleshooting guide and complete the form themselves. This allows us to separate any individual user difficulties from widespread issues that we need to report to Blackboard.

This guide/form should only be used to report issues with Collaborate. If you are experiencing issues with My Dundee or related services, please report these through Help4U.

Collaborate Troubleshooting Guide

Key Information

  1. Ensure you are using a supported browser. Supported browsers are the latest two versions of Chrome, Safari, Edge, and Firefox. (You can use the Blackboard Browser Checker to confirm which browser and version you are using.)
  2. Enable 3rd party cookies. (See BB article which contains links to enable/manage cookies in different browsers.)
  3. Allow Collaborate to access both your video and audio to see and hear others in the session, even if you don’t intend on sharing your own audio or video. (Please change your browser permissions to allow access for eu.bbcollab. com for your audio and video. You may have to be in a Collaborate session to access these browser permissions.)
  4. Confirm Collaborate is connecting to the correct audio and video devices. You may have more than one of these if you’re using an external microphone/headset or webcam. You can learn how to select a device from the Blackboard Audio and Video help pages.

Further help can be found on the Blackboard Collaborate Ultra help pages.

Can’t see the option to join a scheduled Collaborate session

If you have your Ultra module page open too far in advance of the session, the session link won’t automatically appear once the session is open. Please refresh your browser after the start time of the session. If you’re still having issues seeing the link to join your session, please contact your lead instructor to confirm the time and date of the session.

Kicked out of a Collaborate session

Please check your internet connection speed. The university recommends a minimum of 2Mb/s download, 1Mb/s upload.

Can’t share your screen

Application sharing is not available on mobile devices and tablets. If you want to share your screen or application you must be on a desktop computer. (Application Sharing is available on Chrome, Firefox, and Microsoft Edge (Chromium), with no plugins required. It is not yet available in Safari stable releases. It may be made available in a future Safari stable release.)
