Unable to register a brand-new Milesight Gateway

For reference, most (all?) TTN gateways are generally known in the packetbroker service, see also this post:

New API for gateway mapping, status and info

I’m happy to announce that we have a new API for fetching gateway locations, online status and other info for The Things Stack Community Edition, Cloud, Open Source and Enterprise: Packet Broker Mapper. Since we wanted to make gateway information available in one place, we built a new service for this in Packet Broker. With Packet Broker being the backbone for LoRaWAN traffic, making gateway information available in a central place allows for better insight in the entire ecosystem and discovery …

So you can look up a single TTN gateway using (for example):
https://mapper.packetbroker.net/api/v2/gateways/netID=000013,tenantID=ttn,id=eui-24e124fffef55854

Or get all known gateways, then do a search for your own gateway id:
