This can happen when you change your password on the social platform, revoke solnk's access, a refresh token expires, or the platform invalidates the authorization.
solnk automatically refreshes supported tokens and periodically retries recoverable plan-related account states. If the account still shows Need reconnect, open Accounts, choose Reconnect on that specific account, and complete authorization again.
Do not remove the account first unless Reconnect fails. Reconnecting preserves the existing solnk account record; removing it starts a new connection and may affect associated history.
