This article covers guidance for the PEC-AB-0001 error message. You can find guidance for our other error codes here: PEC Errors.

What does it mean?

Your internet service provider is not on our approved list. We're really sorry and we know this isn't your fault.
We're trying to improve this and make all safe connections accessible on Prolific. But for now, you may not be able to take studies from this particular internet connection.

What can I do?

  • Send us a message and we'll add your ISP to our list to be reviewed in future.
  • Try another internet connection (mobile data/hotspot or a friend's house).

Note: Your account hasn't been placed on hold and you can still cash out your rewards.
