MatrikonOPC Redundancy Broker ORB-Ignition 8.1 Connection Issue

Hello everyone,

I am facing some issues while establishing a connection between ignition and MatrikonOPC Server.
The issue comes only when we are trying to establish a redundant OPC connection.
However, the connection works fine when establishing with standalone server.

Below is our system configuration.
Server - 1 (Server2019) :- Siemens Matrikon OPC DA Server
Server - 2 (Server2019) :- Siemens Matrikon OPC DA Server
Client (Windows 10) :- Matrikon Redundancy OPC DA Broker (ORB )
- Ignition Ver 8.1.2
- Matrikon OPC Explorer
We can connect and Browse for all tags in MatrikonOPC Explorer or OPC Expert with “Server1/Siemens Matrikon OPC DA Server” or “Server2/Siemens Matrikon OPC DA Server” or “ORB” nodes.

In Ignition Direct OPC DA connection to “Server1/Siemens Matrikon OPC DA Server” or “Server2/Siemens Matrikon OPC DA Server” is successfull and tags value can also be monitor.
But when we are creating the OPC Connection to ORB node it shows error in connection and shows status faulted.
Error description in Status :
COM object method returns error code: 0x80040154; REGDB_E_CLASSNOTREG (Class not registered)
