Error when changing legacy VB.Net code from InterSystems.Data.CacheClient to InterSystems.Data.IRISClient

#.NET #InterSystems IRIS

I have updated some legacy VB/ASP.NET code and changed the references of InterSystems.Data.CacheClient to InterSystems.Data.IRISClient.  I am struggling with the code as I am not a .NET expert and there is little or no documentation.

I have published the code on several test IIS sites and on some the code works fine but on others I get the below error.   The error doesn't appear to be O/S specific as I have it working on some Windows 2016 servers and not working on other Windows 2016 servers.  I have checked the network card settings as the error seems to refer to IPv6 and IPv6 is not enabled on any of the servers.

None of the discovered or specified addresses match the socket address family.
