On a distributed system, chirpstack-app-server shows “object does not exists" and last seen: "Never"

Hello, I am facing an issue as follows :

@pooja.mittal

Hi @brocaar, we updated to the latest release with bugfixes. Now, two cases were generated:

On the system where chirpstack-network-server , chirpstack-application-server , chirpstack-gateway-bridge were all on one instance/VM , the update made everything work fine.

But on a distributed system, where chirpstack-application-server was on a different instance and chirpstack-network-server + chirpstack-gateway-bridge was on another different instance, we could not see the last seen of the gateways as well as it is not able to get devices from the applications tab, on clicking it is showing “object does not exists.” We checked the host:port in all the config files, and the entries are correct. How can we solve this?

Thank you!

Solved : You have to enter the public_host in the chirpstack-app-server configuration file as internal_ip_of_the_app_server:port instead of localhost:8001 :-

 [application_server.api]
# ip:port to bind the api server
bind="0.0.0.0:8001"
public_host="11.0.0.20:8001"  

After this, update the network-servers in the GUI (don’t need to change it’s value) & check in the loraserver_ns database, if the above public_host entry has been changed in the routing_profile table’s column, as_id .
