rob7419 Posted March 13, 2023 Posted March 13, 2023 I have a program that monitors the heartbeat of the node server and over the last 2 days I have received 3 notification that it has disconnected from the ISY994. All three with the same error and is something I haven't received in the past. 2023-03-13 06:33:45,424 MQTT udi_interface.interface ERROR interface:_startMqtt: MQTT Connection SSLError: EOF occurred in violation of protocol (_ssl.c:2488), Will retry in a few seconds. Both the node server and the admin console show that the two are still connected. The node server completely stops processing data. A node server restart will get everything going again. PG3 is running on a Polisy. Log attached. Debug_detail_03-13-2023.txt
Goose66 Posted March 13, 2023 Posted March 13, 2023 @rob7419 This error is coming from the Polyglot interface (udi_interface) and not the actual node server code. Can you let me know what version of PG3 and what version of ISY you are running? @bpwwer Are we experiencing this MQTT error in other node servers?
bpwwer Posted March 13, 2023 Posted March 13, 2023 There have been other reports of MQTT SSLEOF errors. That error is coming from the Python MQTT library so not something any of our code (node server, udi_interface, or PG3) can do anything to change that.
rob7419 Posted March 14, 2023 Author Posted March 14, 2023 @bpwwerThanks for the update, hopefully a future update to library will resolve the issue. I know this has been mentioned several times in the past, but having the ability to restart a node server in a program from the ISY would be helpfully in scenarios like this one.
Goose66 Posted March 14, 2023 Posted March 14, 2023 I have another minor fix to put into this node server (clearing of notifications on startup), and I am going to rework the node server so that the listener thread doesn't shutdown on these errors since they are technically not fatal (the interface goes to sleep for a few seconds and then retries the connection to PG3). It may miss several state updates, which I know is not ideal for an alarm panel node server, but at least you won't have to restart. I should get to it this weekend.
