I am using cedalo MQTT Broker on ctrlX CORE. The MQTT broker just worked for 2 days and today it promted message "License for Mosquitto Management Center required" when I opened the broker app. This message appeared after I restarted the ctrlX CORE.
Please check the error message and license screenshots.
Solved! Go to Solution.
what version do you use
Do you have other functional apps installed (like Motion, PLC, OPC-UA,...). If yes is their license problem too.
Maybe first you can check the time settings. In older versions there was a problem with the license manager and a wrong time.
The issue persists. The Cedalo MQTT Broker "Management Center" either works as usual or randomly shows the two error messages as shown in figures below.
The time on ctrlX device is also synchronized with a NTP server, so time does not seem to cause the issue. Please have a look at the picture below.
Please let me know about the possible troubleshooting measures. Thanks
