Have you tried with your phone instead of using camera as well as scanner? If you already checked then nothing to say but if you have not yet checked then better check and I think it will be helpful for you. If you cant verify by this way then I don't think they will allow you to verify your identity.

There is an issue with your proof of identity document. We cannot accept the images you have provided due to poor image quality. Please take and upload higher-quality photos of your document making sure that all the information in it is clearly visible and all the document edges are in frame. If your phone or camera can only take low quality photos, you might have to find a better camera. Note that edited images cannot be accepted.
