Upgrade from version 5.23 to 2020.3 - DCOM Issues - by: PythonByte

guys,
my 5.23 version works fine, I just upgraded to version 2020.3 and made the necessary changes and my OPC server application now compiles and runs just like the old version except when I try to connect any client to it, I get the following error in my event viewer :
The server {016D15EB-E0FC-4548-A166-442D9E20048B} did not register with DCOM within the required timeout.

I use Matrikon client to connect and it does try and comes back with can't connect error. I am running everything on the same machine so DCOM is highly unlikely although I did go through the configuration process. Windows Server 2019 is the OS.

If I put the old version 5.23 Matrikon will connect to it just fine. Debugging from VS2019 is revealing nothing and I am looking for either someone will tell me its a bug with Windows Server 2019 or something like this?

I appreciate the suggestions
