Question about non-Arylic product

Hi,
I would like to update my devices using the posted link

…/httpapi.asp?command=SetUpdateServer:http://ota.rakoit.com/third gives OK
…/httpapi.asp?command=getMvRemoteUpdateStatus results in 22
…/httpapi.asp?command=getMvRemoteUpdateStart results in OK but I can hear the message “Firmware upgrade failed” and of course it’s not successful. What am I missing here?
