Product:
Planning Analytics 2.0.4 (TM1)
Microsoft Windows 2016 server

Problem:
TM1 Architect is connecting the TM1 applications on the wrong network card on the Microsoft Windows server.

Possible solution:
The default network card with the lowest metric value is selected from all network cards to be the default network card. Use Get-NetIPInterface to see metrics.

Start Powershell on the Windows server
Enter: Get-NetIPInterface
This will list the network interfaces on the server.
Check the value for ifIndex and InterfaceMetric (A low value indicates a higher priority.)
The card with lowest value for InterfaceMetric will be used by TM1.
Is this the correct one? or is it for a backup network?

12 Ethernet IPv4 1500 10 Enabled Connected ActiveStore
1 Loopback Pseudo-Interface 1 IPv4 4294967295 50 Disabled Connected ActiveStore

Change with Set-NetIPInterface, for example:
Set-NetIPInterface -InterfaceIndex -InterfaceMetric
Example
Set-NetIPInterface -InterfaceIndex 12 -InterfaceMetric 50
Set-NetIPInterface -InterfaceIndex 18 -InterfaceMetric 10
Above will make card 18 to be the new default.
Check the ip address of the card by enter IPCONFIG
