Hi there,
I'm have updated the JWT configuration on the application like that. 
According to this document The refresh token TTL is 1 minute, and the maximum TTL is 3 minutes. Mean that, if I want to refresh the token every minute, I can do that 2 times. Right?
But now, it always returns 400('The refresh_token is invalid.') after the refresh token is created in one minute. (= refresh token TTL ).
Can anyone help me explain this issue, please?
