M-Files COM Error: Network problems are preventing M-Files from communicating with the server. The RPC Server is unavailable

Is this a cloud vault or on-prem?

I hate to be that person but this is typically an issue with the port or network address provided - have you double-checked those against M-Files client running on the same machine? 

Hello Craig and thanks for the response.  This is a cloud vault and I have verified the network address.  I have tried both the ip address and the name. 

I'm going to ask the stupid question again (sorry): are you testing this running on the same machine as the client connection that works?

There is no functional difference, at least in theory, between doing this via code and the M-Files client connection.  If this is being tested on the same machine then there should be no firewall considerations.

What is the protocol and port configured within your M-Files client connection, and what value have you tried in the code?
