This article covers guidance for the PEC-AB-0003 error message. You can find guidance for our other error codes here: PEC Errors.
What does it mean?
You're using a VPN, proxy, or browser extension. These tools are used to anonymise web browsing so they're not allowed on Prolific. Your workplace, public WiFi, or other connections may use these tools.
If you've received this error message, then an automatic hold has been placed on your account.
What can I do?
- Message us as soon as you can and we'll remove the hold.
- Make sure you don't use a VPN when taking part in studies. If you keep using a VPN, your account might be placed on hold permanently.
