If the Console/Monitor failed to inform the ControlUp database (Cloud or On-Premises) about an incident more than 10 minutes, it disposes it and writes an event.
We recommend verifying the connection to the IIS and to the data base are working properly.
In Cloud mode, make sure you do not have any connection failures. If you have a proxy, check its logs and if not, check the firewall\gateway logs.
In On-premises mode, make sure you can connect with no issues from the console\monitor to the on-premises server and from the on-premises server to the SQL server.
