First check the PAIR status page for a known incident.
If no incident is listed
- Check the accepted file type and size shown in the assignment.
- Wait for any processing message to finish before retrying.
- Refresh the assignment and retry once in a current browser.
- Try a private or InPrivate window.
- If your organisation permits it, try another approved browser or network.
Do not disable organisation-managed security controls.
If the upload still fails, contact PAIR Support with the course and assignment names, time of the attempt, browser and device, file type and size, and the exact error or a screenshot. Do not email a confidential assignment unless PAIR provides an approved transfer method.
