Hi all,  
I am quite new with Ignition. I am trying to make an OPC Connection, and I am getting this error (java.lang.Exception). I have been trying a few things I found on this forum, but I could not get it work.  
If someone can give me a hand with this, please. I would really appreciate it.  
Please see attached some screenshot I made.

Thank you very much in advance.

BR

Felipe

This means whatever server you’re trying to connect to expects a username and password but you haven’t configured one.

Hi Kevin. Thank you for your fast reply. Also, I tried that, but it still does not work. I just want to run the OPC UA on my own laptop and connect with a S71200.  
Is there some place where I can recheck all the steps ?  
Thank you in advance.  
Felipe.

What didn't work about it? How did the error message change?

The steps for connecting to most 3rd part OPC UA servers will be similar to those for Kepware: [Connecting to Kepware OPC UA - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/Connecting+to+Kepware+OPC+UA)

Ok, so you probably don't have the correct username and/or password.
