blank screen on my MDM web. Logs provided

Question

Hello,

we have self-hosted hmdm website. Everything was working fine and today we noticed, that our website shows blank screen.

Logs getting spammed 5-10 messages/5seconds. Different ip's all the time and different ports. /var/log/tomcat9/catalina.out logs we get:

[2024-05-06 12:58:42] [info] 2024-05-06 12:58:42 [INFO] org.apache.activemq.broker.TransportConnection : Stopping tcp://xx.xx.x.xxx:47218 because Failed with SecurityException: User name [hmdm] or password is invalid.

Could you assist us with what can we do?

Thanks!

Answer 1

The log message you provided is not related to a blank screen. It tells that the shared key for the MQTT protocol doesn't match the key in the APK. To fix the issue, return the parameter hash.secret to its original value or set the parameter mqtt.auth=0.
