Hi,

I’ve installed and latest TTN. After I added the gateway, I found there are many drop uplink messages error in the gateway’s data tab.

drop unlink mesage (entity not found)

“namespace”: “pkg/gatewayserver”,
“name”: “host_handle”,
“message_format”: “host {host} failed to handle message”,
“attributes”: {
“host”: “cluster”
},
“cause”: {

“correlation_id”: “ad6c57c5be584fe7a3db8c6b74468919”,

},
“code”: 5
}

Also, error keep appear in the server log
