All devices are offline in SUM

Hi everybody,

We have in our office a sum that contain up to 80 devices.

Last wednesday, all this devices become offline.

Please help me to resolve this serious problem.

Please note that is the unique SUM deployed
Note also, that the Cpu usage is not high (between 1% and 20%)

Thanks you in advance.

Hi and thanks a lot for the reply,

When you login to a remote UTM does it show the failed connections in the central management little window?
The internal and remote UTM who are joined to this SUM are showing (Connected) with green mark, but in the SUM, there is no UTM online

Is the address of the sum hardcoded or DNS lookup in the remote sums?
It's DNS record name, and it OK it resolve correctly the address

From another site using your sum (fqn) dns name try to connect to the sum.
It connect perfectlly via the external address

Thanks you for your help

Sorry,for the slow response, I have been working interstate.

Does the log infront of the SUM show any entries successful or failed. What do the logs of the failing UTMs show?
