Probe Health monitor is green yet disconnected



We have a green probe health monitor that says disconnected. How can we fix this? If we restart the service it comes back to normal for a while then again disconnected but green.

Hello Morgano,

Thank you very much for your contact.

What version of PRTG are you currently running? Does the issue affect the PRTG Local Probe or a Remote Probe? Please provide me with a screenshot of the Overview and Logs tab of the affected sensor for further analysis.

Best regards,
