Unable to setup gateway bridge Multitech gateway

Hello and good day to you…

I have multitech conduit gateway. I am trying to install gateway bridge on my gateway by login to my gateway using ssh, and then perform the command:
wget https://artifacts.chirpstack.io/vendor/multitech/conduit/chirpstack-gateway-bridge_3.1.0-r1_arm926ejste.ipk

however, always an error says :

ERROR: The certificate of ‘artifacts.chirpstack.io’ is not trusted.
ERROR: The certificate of ‘artifacts.chirpstack.i’ is not yet activated.b

whenever I try to setup chirpstack gateway bridge or packet forwarder

please, help

Thank you .

Your problem in that.
update ca-certificates or use --no-check-certificate option with wget.

it is solved, Thanks a lot
