Question

I always have this error when I follow ryan’s tutorial to how to use Doorkeeper to protect rest API:

OAuth2::Error: invalid_grant: The provided authorization grant is
invalid, expired, revoked, does not match the redirection URI used in
the authorization request, or was issued to another client.
{“error”:”invalid_grant”,”error_description”:”The provided
authorization grant is invalid, expired, revoked, does not match the
redirection URI used in the authorization request, or was issued to
another client.”}

when I’m in the phase of parsing token. What is the problem and how I can fix this ?

Answer 1

I have an habit of adjusting my time 20 minutes ahead and it’s the source of this problem. Change back the time by synchronizing, now everything works 🙂
