@lorawantesis2022 has posted screen shots of a Kickstarter Gateway earlier. It also shows packets going up but not down. This tells me his gateway server and access key are probably ok.
His screen shot of the TTN Gateway Console does not show his packets getting into the gateway console log although the log shows the gateway connects (except when he switches it off).
Surely the gateway is just using MQTT to send the uplink to the servers? What could stop that? Are the keys checked before forwarding to the application. If so that would suggest his TTN keys may be incorrectly entered on his device.

Please confirm that you have tried using LMIC-node, as asked, and that you have checked your keys are correct note that, below, two DEVEUI and APPEUI are in lsb format but APPKEY is in msb format
