Hi.  
I have installed ignition in my local host and I want to connect matrikon OPC modbus server and DNP3 that is in my VMware, but it doesn't connect. On matrikon I connect Modsim32 via com thru matrikon OPC da.I have done this things below 👇

- use ignition OPC classic, enter IP address of my VMware. Not connecting.
- ping my VMware it's fine.
- tried to connect modscan (host) then modsim (VMware) through tcp..it's fine.
- tried to search in forum, not having similar problem.

Any idea to resolve the issue. Thanks

Assuming your networking setup is okay, have you gone through this guide? [https://support.inductiveautomation.com/hc/en-us/articles/360047134152-Setting-up-and-troubleshooting-OPC-COM-connections](https://support.inductiveautomation.com/hc/en-us/articles/360047134152-Setting-up-and-troubleshooting-OPC-COM-connections)

Is there some reason you're using OPC Classic instead of OPC UA?

Hi Kevin,  
I have done all the steps in the link, but not successful. However some of the steps I can't complete like no1 below.

1. In server setting I can't select "the interactive user"
2. After making new OPC da server, It's shows "connecting" and after 1 min "faulted"
