Hi
I am getting an error, when I use my fingerprint reader on my VTO4202F. Can you help me figer out what the problem is?

I am not sure if it is related, but the script loses the connection to the mqtt broker:
2022-06-02 23:02:59,198 INFO clients.DahuaClient Server sent EOF message 2022-06-02 23:02:59,208 WARNING __main__ Disconnected, will try to connect in 5 seconds 2022-06-02 23:03:04,214 INFO __main__ Connecting 2022-06-02 23:03:04,221 INFO clients.MQTTClient MQTT Broker is trying to connect... 2022-06-02 23:03:04,224 WARNING clients.MQTTClient MQTT Broker got disconnected, Reason Code: 7 - The connection was lost 2022-06-02 23:03:04,231 INFO clients.MQTTClient MQTT Broker connected with result code 0

where do I find the log?

[elad-bar]

From time to time the MQTT can disconnect clients, that means it automatically reconnected

[matlab22]

In my case it does not reconnect:

when I restart the script it reconnects instantly but I am getting this message:
2022-06-16 21:04:22,254 INFO clients.DahuaClient Device Type: VTO4202F 2022-06-16 21:04:22,255 ERROR clients.DahuaClient Failed to handle message, error: 'NoneType' object has no attribute 'get', Line: 76

[matlab22]

is there anything I can try. This happens very often and it can not reconnect automatically. The mqtt broker is stable I use it with my zigbee devices all the time

[matlab22]

It lost connection and never try to reconnect:

it looks like it can connect but not properly. so it never goes in the exception of "while not self.is_connected:"
How do i know what reason code 7 means?

[elad-bar]

I will check it later today,
Error 7 is connection lost, most probably by the broker,
Seems that the issue related to first message in the log dump

[matlab22]

Perfect thank you. I guess the message is too long so it is not getting fully parsed.
