A site server registered to NX Cloud successfully.  However, this site shows as “offline” in NX Cloud.  Some tests have been performed:

1. Local server can access to NX Cloud via browser, and able to see other sites info & video;

2. Local server Desktop Client cannot access to other site server

3. NX Cloud from outside network cannot access to this problematic site server (shows offline).

Please advise.  Thanks.

  Hi Raymond Wan,

  The most common cause is a firewall, proxy, or web-filtering or antivirus product that allows browser traffic but blocks the Mediator and Relay endpoints. 

  Please do the following on the affected Server:

  1. Confirm that the Server’s date and time are correct. If the clock is wrong, secure connections to the Cloud fail.
  2. In the Desktop Client, open Main Menu > Site Administration > Cloud and confirm that the Site still shows as connected to the Cloud.
  3. Run the Connectivity Service Checker on the Server. You can find the script and instructions here.
  4. If any endpoint isn’t reported as AVAILABLE, ask your network administrator to add all of the listed FQDNs to the firewall allow list.

  Best regards.
