KB-2186 "Infrastructure: Environment Removed" email received but no users report removing the connected environment


System Administrators receive an email that reads, "An environment in your infrastructure has been removed", but no system administrators report removing the configuration. 

Additionally, the user who set up the connection is logged in the devops_infrastructure.csv log as the user who removed the connection. An HTTP 404 is also observed at /suite/devops-infrastructure/handlers in the tomcat-access.log of the remote environment:

YYYY-MM-DD HH:MM:SS /suite/devops-infrastructure/handlers - 404 X.XXX


When Appian receives a HTTP 404 at the /suite/devops-infrastructure/handlers url, Appian will automatically remove the connected environment.


Re-add the connected environment in the Admin Console.

Affected Versions

This article applies to Appian 19.1 and later
