You are probably talking about the old tracker settings now. They have been updated and are supported only for previously configured units.
At the moment, to configure the tracker Queclink GL300 you need to choose:
Device Category - Hardware
Device Type - Queclink GL300
After this, you need to configure the tracker to
11746.flespi.gw (DNS server format, if the tracker does not support it, then you need to configure the tracker to the IP format)
126.96.36.199 (IP server format)
