To resolve this issue, remove the above <security-constraint> directive from the file referenced above, and instead, place it in the file <Nimsoft>\probes\service\wasp\webapps\ROOT\WEB-INF\web.xml instead, it will work properly while still allowing UMP requests to be redirected to HTTPS appropriately.
It is also possible for this message to be returned when the ACLs need to be reset. To do this open Infrastructure Manager, and go to Security-> Manage ACLs.
From here, click "OK" without making any changes.
This causes a reset of the user permissions and corrects the issue.
