Join requests received are considered as unexpected #2122
Description
Expected Behavior
I install two different gateways on the same Network.
The first one (lbs version 2.0.5) handle properly each device we work with.
The second has a different version of LBS (2.0.6) should also work (same configurations, same deployment).
Current Behavior
Join Requests handled by the second gateway are considered as "unexpected" by the LNS.

Logs
We notice an additional parameter in the Join Request from the 2nd Gateway: "fts"
Here is a join request from the operational Gateway:
<GatewayID> Received 'jreq' message: '{"msgtype":"jreq","MHdr":0,"JoinEui":"<JoinEUI>","DevEui":"<DevEUI>","DevNonce":18307,"MIC":1914631336,"RefTime":0.000000,"DR":5,"Freq":470700000,"upinfo":{"rctx":0,"xtime":25332748023622995,"gpstime":0,"rssi":-40,"snr":9.5,"rxtime":1704768074.358533}}'.
Here a "failing" join request from the 2nd Gateway:
