You may encounter a problem a monitoring point in your organization which appears to be unable to connect, and gives an error message suggesting a blacklist:


There is a variety of variable that could cause this issue, but the AppNeta SaaS portal may block a monitoring point from connecting to AppNeta if it repeatedly establishes and drops connections (10 connections within 5 minutes). 

This could be an issue with the local monitoring point's internet connection itself, or routing issues when attempting to reach the target AppNeta server.


The blacklisting is temporary, and is lifted in 4 hours time.  When the blacklisting is removed, the monitoring point will be able to attempt to reconnect, but keep in mind if there is ongoing connectivity issues, it could result in another blacklist.

To investigate the issue, you may want to confirm the monitoring point is able to connect to the internet.  If so, the next step may be to check the Monitoring Point's Admin portal and run Server Reachability Test:

Other ways to review what may be causing this issues, is to consider setting up a delivery path to the AppNeta app server:

You can leverage the AppNeta tool to monitor the appliance's health of sending information back to AppNeta.  This may be useful if the monitoring point is having data loss or other performance issues.
