Hi,
I am trying to configure OPC UA Server connection from Ignition 8,13 Vision to Cogent DataHub OPC UA server.
No any issues if I use laptop with Ignition Trial version.
After entering the endpoint URL, I get these options (means connection is established):
However, at next step error pops up:
Found this article, but did not help:
Wireshark could not help either.
Any ideas?
Is there no alternative to select in that next step? This is probably happening because the hostname can’t be resolved, but usually you should get an option to proceed using the IP you originally used to discover.
What happens if you select the “Substitute URL From Discovery” option?
Is there some error in the Ignition Gateway logs?

Can you get a Wireshark capture while you attempt this? As far as I can tell this error is coming from the server for some reason...
Thank you for your always activ support, Kevin.
Okay, in that step where you can select "Use another URL", try
opc.tcp://192.168.33.99:51310/CogentDataHub/DataAccess
and not just the IP:port.
If that doesn't work you might need to contact Cogent support, because I can't see why else it might return a ServiceFault in response to a GetEndpointsRequest.
Worked like charm. Thanks a lot!
