MQTT issue

Hi,

I've successfully configured MQTT in Cumlulus (v. 3.8.3) but it only worked for a few hours. Now, no more communications between Cumulus and the MQTT broker/server (installed on the same machine) and no errors displayed in MXdiags log (no errors in MQTT broker log). The MQTT broker still works fine with other services. Also tryed with another MQTT on different machine with no success.

Any suggestions?


Have a good one,
Davide

The problem was caused by the fact that I'd changed the address of the MQTT server using the IP instead of the hostname. Going back in the changes (after a Cumulus reboot) everything's back to normal.


Edit - of tipic:
I made a suggestion for "retained message" here:
