Unexpected cloud error (PE253)



Is there something wrong with the HTTP and HTTPS cloud sensors today? All of ours went offline with the error message listed in title. Our PRTG installation is up to date.

Hi there,

It was an issue on our end. In case the sensors do not come up again on their own, flush the dns cache using ipconfig /flushdns in command prompt on the regarding probe that runs the sensors.

Kind regards,
