[HELP] Сommunication failure between the gateway and TB after 6 days of normal communication

[pro100805]

Everything works fine for 6 days and then TB stops seeing GW. The GW continues to poll devices and receive telemetry normally

gateway polls devices using serial port Modbus RTU protocol

restarting the gateway or TB does not bring any result. After a complete reboot of the system the situation repeats, everything works fine for about 6 days

the same server and gateway using communication with Modbus TCP/IP devices works without problems

Hi @pro100805,

Thank you for your interest in ThingsBoard IoT Gateway.
Could you check that you are using the latest version of tb-mqtt-client?
You can do this using the following command:

pip show tb-mqtt-client

Version should be 1.10.8 at least, if it is older you can update it manually, using the following command:

pip install —upgrade tb-mqtt-client

Please try to update the client, restart and then check after the same period of time, it should be solved.

thanks for the quick response
version was 1.9.9, updated to see what the result will be
there is a small typo in the command, one “-” is missing.
pip install --upgrade tb-mqtt-client
You continue to exceed every expectation that we set. Great job.
