Following the documentation I have achived to obtain a token with post 01 – Authorize Code Grant and I have used Get 04 User Info to obtain the data from my user in DocuSign (perfect) the problem is that after two days I want try it again but the system answer me “internal_server_error”

Could you be the problem of the Token ¿???? I´m not sure if in a video a listen that the token live 8 hours, is it ¿???
I have tried to use the post 03 – Refresh Access Token (when I obtained the token also I obtained the refresh Token)
But the answer is invalid grant

Could be that for obtain a new token and using the post 03 Refresh Access Token after 8 hours it is no valid more ¿???
Now I´m watching the video Get an Access token with JWT Authenticacion (Using this obtaining the token, is it possible needn´t obtain more tokens ¿????? Or I need to refresh the token or anything else .

Any help or suggestion ¿???? Thanks in advance. Sorry for my english ¡!!!!
