End node cjoin:Fail

Hello.
First of all, have a good day everyone. I am new to lorawan and i am trying to send uplink downlink messages. I was able to connect the gateway with ttn. But I get join failed error on end node side.
Lorawan module:e78-868ln22s
Gateway: dragino-lps8 indoor gateway

End node AT commands:

+CGBR:115200
+CJOINMODE:0
+CDEVEUI: xxxxxxxxxxxxxxxx
+CAPPEUI: xxxxxxxxxxxxxxxx
+CAPPKEY: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+CDEVADDR:xxxxxxxx
+CAPPSKEY:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+CNWKSKEY:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+CFREQBANDMASK:0001
+CULDLMODE:1
+CWORKMODE:2
+CCLASS:2
+CBL:100
+CJOIN:1,1,10,8
+CSTATUS:05

I’m pretty sure the deveui appeui appkey values ​​are mapped on both sides. Why does this problem occur and how can I fix it.
