Invalid access token field/s: the 'aud' is invalid --- just for single student

Hi,

I've been using LTI 1.3 to passback grades successfully from my application to Canvas and have just encountered something a bit odd.  As the title suggests, I'm getting "Invalid access token field/s: the 'aud' is invalid" but this is only for a single student at the university.  They all have the same *.edu email.  Any thoughts would be appreciated.

Thank you,

 

Eric
