needing help with connecting a lorawan gateway to openremote

Good day all, I am trying to connect my gateway to openremote with mqtt. It looks like I have got the mqtt explorer to connect to openremote
This is the mqtt explorer and when I say connect it does

this is my gateway settings but does not connect

I tried to put the self assigned certificate but for the tls but its like it does not recognize it. any suggestions that could work?

with the gateway I am able to set the uplink topic and downlink topic


what would be the best topic for these that open remote will handle.
