+## ConnectionLostException - NameRenewalFailed
+
+### Symptoms
+Your client receives the exception: `Microsoft.Azure.Relay.ConnectionLostException : InternalServerError: NameRenewalFailed`.
+
+### Cause
+Azure Relay service restarts listener connections every 24 hours. This behavior is by design. The Azure Relay service disconnects a listener active connection every 24 hours, and the listener will reconnect with the server using the retry mechanism.
+ 
+### Resolution
+No action on your part as the listener automatically reconnects to the server. If you notice that your listener isn't connecting again, [submit a ticket](https://azure.microsoft.com/support/options/) to the support team.
