after further test, it seems there is a problem when using curl PHP to post the image to the face match server. i have tried on multiple servers and it's giving a problem.

what's work for me is i change the method from using curl to using pear http_request2 method and i'm also using my own image library to compare with webcam snapshot not using the image from user profile upload. i also change the image size for the webcam snapshot to a bigger size.

Did you set your profile picture first ? you need to set your profile picture to be able to compare your camshot. We did not find any issue with BS face match. please see the below screenshot where facematch was successful.

Please check if following things are set up correctly before trying facematch.

Your profile picture is set
Facematch is enabled in proctoring settings. See the below screenshot.
BS URL and token is setup correctly in settings

As we did not find any issue we are closing this issue.
