Connection issue #86

Closed drhexium closed 8 years ago

drhexium commented 8 years ago

I am trying to run ver 0.12.0 but I am getting the following error:

Sep 26 13:49:36 saide-gtw loraserver[1437]: time="2016-09-26T13:49:36+03:00" level=info msg="grpc: addrConn.resetTransport failed to create client transport: connection error: desc = \"transport: dial tcp 127.0.0.1:8001: getsockopt: connection refused\"; Reconnecting to {\"127.0.0.1:8001\" }"

For information, I run this on a Raspberry Pi 3.

BTW: version 0.11.0 seems to work fine.

Thanks!

brocaar commented 8 years ago

That is because you need to start the lora-app-server too (which is running by default on port 8001). Please see the changelog for instructions to migrate from 0.11 to 0.12 as it describes how you can migrate your data and node-sessions.

Brocaar, Thanks for the immediate response. I have now started lora-app-server and I am getting the following error: Sep 26 14:20:06 saide-gtw lora-app-server[1750]: time="2016-09-26T14:20:06+03:00" level=info msg="grpc: addrConn.resetTransport failed to create client transport: connection error: desc = \"transport: dial tcp 127.0.0.1:8000: getsockopt: connection refused\"; Reconnecting to {\"127.0.0.1:8000\" }"

loraserver (0.12.0) seems to be working fine though

Is should mention that on the same host (Raspberry Pi) I am also running the packet-forwarder and lora-gateway-bridge (in case this causes any problems).

Sorry if I am doing something stupid :-)

brocaar commented 8 years ago

That is the other way around, the lora-app-server trying to connect to loraserver. Please note that you can't avoid these errors as it is kind of a chicken egg problem. However it will try to re-connect and these error should stop as soon as both services are connected to each other.

Actually, I do not see these errors ever stopping even after both services have started.

Some of the errors that I am getting:

Sep 26 14:46:56 saide-gtw lora-app-server[2749]: time="2016-09-26T14:46:56+03:00" level=info msg="grpc: addrConn.resetTransport failed to create client transport: connection error: desc = \"transport: dial tcp [::1]:8080: getsockopt: connection refused\"; Reconnecting to {\"localhost:8080\" }"

Also when trying to access the configuration page through a browser pointing at serveraddress:8080 I get this: Sep 26 14:47:14 saide-gtw lora-app-server[2749]: 2016/09/26 14:47:14 http: TLS handshake error from 10.22.71.146:55280: tls: first record does not look like a TLS handshake

Thanks

brocaar commented 8 years ago

Ignore the 8080 error (this is an internal connection error which only happens at startup and is automatically resolved, basically the REST api can't connect internally to the gRPC server). You're almost there, try to point your browser to https://serveraddress:8080/. (note the https).

It worked! Thanks!!!!

Just one (hopefully) final question: - How can I check the incoming data? I cannot find the "Transmitting/Receiving Data" sections on the updated documentation. Could you point to the right direction?

Thanks again!

brocaar commented 8 years ago

Great! See https://docs.loraserver.io/lora-app-server/mqtt-topics/
