OPC UA Client Certificate Issue

[Jiraiya_Sensei]

I am trying to connect to a 3rd-Party OPC UA Server via LabVIEW OPC UA Toolkit. I am currently trying to show a demo to my teammates on the advantages of LabVIEW using Trial Version. My certificate for the Server machine from Client is getting generated. And I have pasted that in the appropriate folder of my server. For my Client which is a LabVIEW Machine. I am getting the below error (snip attached) when tried to run the VI. I guess it is due to the certificate of the Server is not trusted ? And I read some online such solutions for the same. But I am not sure on where do I need to paste my Server Trusted Certificate in my LabVIEW Client Application machine. 

I also used the Demo Project but issue remain the same. Not sure where am I going wrong ! A guidance in this regard would be appreciated.

I know some Rockwell OPC UA Servers don't have names that really are intuitive. Have you tried using a 3rd party client just to read the data and confirm your setup (name and such) is right?

Sorry I can't help on the certificate side.
