Starting on Saturday July 5 there was an issue with a firewall blocking traffic to the server used to deliver automatic updates to the CloudLink Gateway and CloudLink Daemon. This would not have impacted day-to-day operations and would only be seen if you were trying to apply updates or deploy a brand new system. We identified and disabled this firewall this morning at 9:00 UTC-0400 and observed all traffic was flowing correctly again.
This incident has been resolved.
