Hello,
I am struggling with 'unspecified error', E_FAIL when I try to connect to OPC Server from the client code running in VisualStudio 2017. Entire session is running on single machine.
unspecified error is really not giving enough information to understand reason behind. so I wonder whether anyone knows how to diagnose or enrich provided information so we can proceed with opc client testing.
Both OPC Server and OPC Client are Kepware and client is based on ClientACE.
Nothing is wrong with the code as it worked when deployed on target environment / staging and / or production.
thanks in advance.
