Not Receiving Access token anymore

Yesterday, I set up the sample app and got everything to work with the auth and was able to sign into the app, but camera streaming wasn't working. The log just outputs "Initiating Camera Stream call to Device Access API". Now today the I'm not receiving an access token and the logs are outputting:
`
{
"error": "invalid_grant",
"error_description": "Bad Request"
}
`

I've tried changing out the oauth client id, changing the project on device access console, and still getting the same response.

Does anybody have a solution for this?
