Error: user for app is not enabled when refreshing access token

[ol_minhkhau]

When I refresh my access token using this API

curl https://api.dropbox.com/oauth2/token \
    -d grant_type=refresh_token \
    -d refresh_token=<REFRESH_TOKEN> \
    -d client_id=<APP_KEY> \
    -d client_secret=<APP_SECRET>

I get this error: user for app is not enabled.

I can't find information about this error anywhere in the documentation or somewhere else on the Internet.

Please help me. What are the possible causes of this error and how could I troubleshoot it? Thanks.

That error for this call indicates that this failed because the account that owns the app for that refresh token/app key/app secret is disabled. When an account is disabled, any apps owned by the account are also effectively disabled.

You'll need to instead get and use a refresh token/app key/app secret for an active app owned by an active account.
