Looks like the server you are connecting to doesn’t allow anonymous identities and you didn’t provide a username and password.

No, Ignition's OPC UA server has its own authentication profile. The default username and password are `opcuauser` / `password`.

I changed the username and password to the default and it still didnot work. I have a feeling I might be a little confused on the endpoints... what should be the end points,  
Should my OPC-UA endpoints for the ignition and kepware have the same network ID?, and just different end points? They're both installed on the same PC
