Sometimes the information that Cloudpress uses to connect to an account can become invalid. For example, an administrator may revoke the access token you used to connect your CMS account or change your password. In such cases, Cloudpress cannot export content to that account until you reconnect it.
You can reconnect an account by going to the Connection tab on the connection detail page.
As you can see in the screenshot above, Cloudpress will indicate if there is a problem with the connection. Follow the instructions to reconnect the account.
