Hello Bob,
On the Conduit, can you ping the host that you are trying to connect to with the http request node? Usually the ESRCH tends to indicate a problem with DNS or a proxy being used to forward DNS.
For the LoRa-IN node/MQTT messages this is most likely due to the upgrade of several packages (Mosquitto and libmqtt). I have seen this same kind of reconnect behavior in other (C++) code doing MQTT. Something in libmqtt seems to time out the MQTT connections or something. It appears to me that the “re-connects” don’t seem to be harming anything.
