Steps I've Taken

Attempted to sign in using Google authentication
Received the error message described above
Tried clearing browser cache/cookies with the same result

Browser/Environment Information

Could this be a configuration issue with the OAuth client settings? I'd appreciate any guidance on how to resolve this so I can access the application.

Thank you for your help!
