A new timer is implemented in Maxwell software 2.13, which is available via provisioning and Web-UI. The new timer shall restart the sending of SUBSCRIBE messages, if they have failed. Failed Subscription Retry TimerDefault: 300 seconds Range: 0-9999 seconds The "Failed Subscription Retry Timer" determines the time when the device starts with a new subscription attempt after the previous attempt failed. Two cases must be respected: - The SUBSCRIPTION was rejected through a 4xx, 5xx, 6xx status code.
The timer is fired and the device waits with a new subscription attempt until the time expired. - The SUBSCRIBE was not responded
The device repeats the subscription in the following interval: 2.1 - 0,5 s, 1 s, 2 s, 4 s, 4 s, 4 s, 4 s, 4 s, 4 s, 4 s - 2.2 - Afterwards it waits until the Failed Subscription Time elapsed (e.g. 300 seconds) and starts with the interval again.
