The Recording Server where the device is connected is behind a firewall. In order to access the device through a firewall using Interconnect, you must create a firewall exception. To do so:
1) Open Windows Defender Firewall with Advanced Security (%windir%\system32\WF.msc).
2) Create a New Inbound Rule (left-click on Inbound Rule).
3) Select "Port" as type of rule
4) Select "UDP" to apply the rule and Specific local ports: "443"
5) Select Allow the connection.
6) Select the appropriate connection type where the rule will apply.
7) Specify a name for the rule: "Milestone Interconnect - UDP Port 443".
8) The device should be connected now.
Note: Connection type must be the one that the Recording Servers use to establish the link.
The rule must look like this.
