Monitor Knowledgebase

Summary

The per-second rate of failed attempts to authenticate with the relay over UDP.

Causes

This error occurs when there is unexpectedly high rate of message authentication failures over UDP. This could be the result of a configuration error or an attempt to misuse the A/V Edge Server.

Resolutions

If the A/V Edge Server is deployed in a load balanced array verify that the same authentication certificate is deployed on each machine. Check that the profile of network traffic to the A/V Edge Server is in line with expected usage. A network level trace can be used to determine if there is unusual amount of traffic originating from a single source. If the situation persists then enable tracing to identify the originator of messages failing authentication checks to allow further troubleshooting of the cause.
