[Observium] Device Showing Down in Alerts but Device is online

Hi Team,

We have problem with device alerts. Due to this we can't monitor our network. Actually, our devices are online but, in the alerts, it will be showing down. I have tried to forceful discover but still same. I think it will be software bug then i will update to latest version but at here also same issue. If anyone have solution, please let me know. Thanks in advance.
