Hello Wendy Chuang

We have again a NxCloud problem

A site that you got access (about my ticket #35140 - Brion) cannot be reconnected to NxCloud (customer call me that his system is seen "offline" on NxCloud)

I can get a remote access and make a soft-reset for the server but I still get offline on NxCloud

Under ubuntu and Nx 5.1.0.37133

 

Because I cannot get files from my remote NxWitness : I get this logs on monitoring logs.

  Loïc TONON : le support Nx n'a pas l'air de réagir et le client ne comprend pas pourquoi du jour au lendemain, il ne peut plus se connecter à son site ...

  Hi, 

  After use a local nxwitness, Nxwitness cannot access to internet because of no dns from router. I don't understand why, because Teamviewer which is very sensitive to dns problem works fine.

  Customer hard reboot the 4G router and the connection has been reactivated and operationnal.
