If you received this alert it means your ControlUp Monitor service is running successfully and does connect to our configuration servers BUT does not upload probably due to a connection issue with our S3 bucket at Amazon's AWS.
You'll probably see this error in the Monitor settings screen:
Please verify that the machine running the monitor can reach *.amazonaws.com on port 443 (https).
If not, please open the firewall port and white-list it in the proxy.
NOTE: The AWS URL is essential for data upload to Insights. The dynamic IP range of the S3 URL changes according to AWS policies.
