Please give me the solution.

It seems like you’ve changed a lot of port configurations and somewhere made a misconfiguration. Make sure that in the LoRa App Server config:

--as-public-server value         ip:port of the application-server api (used by LoRa Server to connect back to LoRa App Server) (default: "localhost:8001")

Is configured at the same port as --bind.

After updating and restarting. Go in the web-interfaces to network-servers. Click on the network-server record and click the save button. That will update the routing-profile record stored in LoRa Server.

Hi,
Thanks for your reply.
Please tell me in web UI while creating network server what i have to give for network-server server. ?

#7

The hostname:ip to the LoRa Server API (same port as LoRa Server --bind config). But probably the value is already correct. First try to just save it again after updating the --as-public-server setting (and restarting LoRa App Server).

Hi,
Thanks for your help and support. Now am getting the decrypted data in mqtt topic.
After u suggested me i made -server api and –bind value same and then i got the result.
Thank you soo much once again:grinning:
