Gateway not initializing connectors due to empty remote config payload

[rahulrgd18]

Hi team,

I'm running into an issue with ThingsBoard Gateway where one instance works correctly, but a second gateway fails to initialize any connectors. Both are configured similarly and connected to the same ThingsBoard platform.

✅ Working Gateway Logs (partial):

Remote Configurator started  
Gateway connectors initialized  
Persistent devices loaded  
Gateway started  
Requested remote configuration received, keys: ['MODBUS 5', 'active_connectors', 'MODBUS 2', ...]  
Error on loading connector 'MODBUS 5': 'master'  
KeyError: 'type'  

Despite these errors, the gateway continues to operate and push data.

---

❌ Failing Gateway Logs:

Remote configuration received, key: []  
No connector initialization  
No MODBUS activity  
Gateway shuts down shortly after startup  

What I’ve Checked:

• MQTT connection is successful
• Remote config is enabled
• Local config files are identical
• Platform version is the same for both gateways

My Question:

Is there a known dependency between the ThingsBoard platform version and the gateway version that could cause remote configuration to fail silently like this? Could an outdated gateway misinterpret the config payload or ignore it entirely?

Any guidance or suggestions would be appreciated. I can share full logs or config files if needed.

Thanks in advance!

Hi @rahulrgd18, thanks for your interest in ThingsBoard IoT Gateway!
Are you trying to connect two gateways with the same access token to ThingsBoard?

[rahulrgd18]

The issue is resolved now. I realized I was using the Slave token instead of the Gateway token — that was the main cause of the problem.
