Refresh token doesn't always work with API v3

Occasional Participant

Why does token refresh doesn't always work? We always have to reauthorize.

When a token expires and then we try to refresh it, we always get the below error and mind you, it is the same refresh token given to us when we requested for an access token.

{\"error_description\":\"unknown, invalid, or expired refresh token\",\"error\":\"invalid_grant\"}\r\n."}

Bumping this question as well.


We've been struggling with this issue on several sites. The documentation is pretty clear about the lifespan of the token types; however, when attempting to use the API more than a day later the refresh token returns the same response as the OP noted, and we're forced to perform a complete re-connection again. Where's this breaking down?
