When you configure a device with a new server address, you need to reboot the device in order to connect to the new server, which you can do by sending it a “cpureset” command.
The issue is simple: The setparam command successfully saved the new server settings to device memory, but the device needs to be rebooted for these changes to take effect. The device is still maintaining its active connection to the old server until it restarts.
Solution
Send the following SMS command to each device:
cpureset
Important notes:
Before SMS text, two space symbols should be inserted (if no username/password is configured on the device)
If you have a username and password configured, use: username password cpureset
The device will not send a response to this command - it will simply reboot
After reboot, the device will connect to the new server you configured
