hey everyone
I have 2 lorawan gw(named A and B),using AS923-2-NDT(AS923-2 freq plan has test,fail…)
i have build a multicast device
then I use mqtt client login and send multicast msg ,if the gateway_id is A’s ID ,work fine ,multicast msg can downlink from gw A
but when i change to B’s ID , I got this err

question 2:

i check a lot of TTN document page,failed to get the usage help msg
this is my cmd
ttn-lw-cli end-devices downlink push jack-au915 multicast-as923-2 --class-b-c.gateways eui-ac1f09fffe0166b7-2 --f-port 10 --priority NORMAL --frm-payload 112233445566 --log.level debug
the eui-ac1f09fffe0166b7-2 is my gw id
