Some days ago I developed an integration with DocuSign, and then I got my token with RequestJWTUserToken and sent some emails with my code.
From today on, I can't send emails anymore, I also tried making a new request to get a new token, but when I call CreateEnvelope method, I get this error:

```
{"errorCode":"USER_AUTHENTICATION_FAILED",
 "message":"One or both of Username and Password are invalid. Invalid access token"}

```

It looks like my token doesn't have permission
