I have a system whereby i have various Ignition Edge gateways, installed with MQTT transmission module. On my server, i have MQTT engine and distributor installed. All communication is fine.
When there is a power shutdown, edge gateway is forced to off, and then manually started back on. When the edge gateway is back on, the MQTT transmission seems to be stopped sending messages to the server. I would have to manually restart the MQTT transmittion module to refresh the communication status, then only it would start sending messages to the server again. Sometimes, the communication could only be restored during the second module restart attempt.
Would like to know, is this a normal behavior?
If not, could someone kindly advise how should i go about troubleshooting this issue?
Many thanks in advance!
