[HELP] Сommunication failure between the gateway and TB after 5 days of normal communication
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.
Good day, unfortunately the situation is the same again, GW continues to receive data normally, but the connection with TB is broken. 5 days of normal operation and then this situation. what additional information can I give you to sort this out?
I see also an issue with the connection to Thingsboard. If the MQTT transport is not available for some reason, it seems the GW does not reconnect properly if the IP of the MQTT transport changes. This is odd because i have configured a hostname in GW for the MQTT transport.
