Connected incident <Incident Number> is in Resolved state while the alert is Reopened. There is no matching alert rule to reopen the incident. Disconnecting the incident from the alert Release All releases Environment Event Management plugin is installed Cause One reason would be not defining the alert rule correctly.For example, we might add State is Open in the Alert filter condition as below. Resolution When an alert is reopened, the state of the alert would be 'Reopen' not 'Open' and hence the alert would not match to Alert rules/Alert Management rules and hence the message is thrown and the incident is not opened.Hence modify the alert accordingly by adding another condition to include State is Reopen or dont not include the state fieldin the rule.
