If you face the issue above, you can still entering off-line and operating in Spark. But if the reports are still empty once you get in, the most likely reason is that your IP is new and has not been whitelisted yet.
1. Check your internet connection and launch your VPN application if you have it. Then open again Spark.
2. If it is still not working, or you don’t have a VPN, send your IP to support@athenasystems.com asking them to add it for you. You can check your IP here.
