Dial application-server api error: context deadline exceeded

Hello everybody,

for my studies i am currently dealing with Lora.

I use a Dragino LG01-N as a gateway and want to connect it to the Chirpstack server.

Two days ago I connected it to the server and it was shown to me as online.

The next day i wanted to make further configurations, but although I did not change any of the settings, I received an error message that I am stuck with.

I use everything under localhost in a virtual machine (opensuse)
and have taken over the settings as they are in github without changing anything.

I would be very happy to receive an answer.

best regards, Johannes

I believe this error has been covered by a few topics already: https://forum.chirpstack.io/search?q=get%20application-server%20client%20error.

If everything is running on localhost, then "chirpstack-application-server:8001" is not a correct value, as this hostname does not exist (it works when using the Docker example).

To setup everything within a VM, please have a look at the Debian / Ubuntu tutorial: https://www.chirpstack.io/guides/debian-ubuntu/.
