[HELP] Can't send RPC command {"error":"NO_ACTIVE_CONNECTION"}

[Altamirano426]

Hello everybody, When the Docker container for tb-gateway (version 3.2) is started, if I send an RPC command to a device provisioned on ThingsBoard(latest version), I am correctly notified on the gateway. However when the gateway is restarted, RPC messages are no longer notified to the devices through the gateway. In such a scenario, ThingsBoard returns a connection timeout error and prints the following log.

I have the same problem. Solution using "Overwrite activity time for connected device", does not work

Hi @Altamirano426 @mdameda, do you have enabled Remote Logging?

[Altamirano426]

hi @samson0v, yes i have all the logs in case it's needed.

Hi Team I am running RPi device which is the mqtt broker for the Gateway itself. It is working fine, at least that part. I have the following issue, I can send telemetry MQTT->GW->TB->Dashboard. But I cannot receive any RPC call from server. I have the default config. and remote logging (which has a handler issue). and I am wondering what am I missing here , why I cannot receive any RPC from server/dashboard round switch.

This is the portion of my mqtt.json config related to serverSideRpc. and a second doubt would be, is needed the rpc_connector.json connector to make it work? I am kind of lost here with this... thanks I am not understanding thanks in advance for any comments or suggestion.

• TB Server ver 3.6.4 running on ubuntu 20.04

• TBGW python install running on RPi3B+ - python ver 3.11.2 - RPi OS"Debian GNU/Linux 12 (bookworm)" nodered ver 4.0

  "serverSideRpc": [ { "deviceNameFilter": ".", "methodFilter": "echo", "requestTopicExpression": "/sensor/${deviceName}/request/${methodName}/${requestId}", "responseTopicExpression": "/sensor/${deviceName}/response/${methodName}/${requestId}", "responseTimeout": 10000, "valueExpression": "${params}" }, { "deviceNameFilter": ".", "methodFilter": "no-reply", "requestTopicExpression": "/sensor/${deviceName}/request/${methodName}/${requestId}", "valueExpression": "${params}" } ],

I have been playing around a bit more, Installed a new GW in ubuntu 20.04 just to make sure... the behaviour is the same I cannot get any RPC or any attribute from server side either... looks like from GW to TB Server is fine, but not the other way round... thanks again guys
