Wyse 3040 client does not apply WMS group settings immediately


I have a phenomenon here that a Wyse 3040 client does not immediately apply the changes I make in a group in WMS.

However, on the client, if I briefly open the WMS settings in the Central Configuration area once and directly close it again with OK, the settings are immediately applied by the WMS.

It doesn't matter what I want to do: Send message to the client, change hostname, etc. Everything is done only when I go to the WMS settings on the client once and click OK again.


What could be the reason for this?

Best Regards,

Is it possible that the problem is related to the apparent lack of connection to the MQTT server?

MQTT (port 1883) is the real time communications channel used to notify the endpoint that a change is a need and to contact the WMS server on port 443 to receive the pay load. 

If you have a communications issue on MQTT then the changes would be received on next full check in (usually an hour) or a reboot.
