Hey All,
I recently was looking at my OPC-UA settings, when I hit save (after changing to read only) I exited and the connection went to Faulted instead of connected. I went back into the settings and changed everything back to the default settings to try and see if there was a way to reconnect but no dice on that end either. So I tried deleting that connection in hopes that a brand new connection with default settings would be able connect no problem, following the steps laid out in the 7.9 manual. Again no dice so I’m a bit stuck as to what caused this faulting to occur. When I look at the details surrounding this issue I get the following message “status=Bad_UserAccessDenied, description=User does not have permission to perform the requested operation.”
Any insight to this would be much appreciated, thanks.

Does your gateway still have the ‘opcua-module’ user source?
Also, under Configure → OPC-UA Server → Settings, is this authentication profile assigned to Ignition’s OPC-UA server?
If both of those are true, is there an actual user inside the ‘opcua-module’ user source? The default user is ‘opcuauser’ with password ‘password’.

All of that is true. The connection is back up and running, after again not changing anything. Holding my breath and hoping that it stays that way.
Yeah. I found it to be the case too that the OPC-UA server seems to randomly stop. Usually clicking edit and saving solves it but once I had to reset the module. This seems to be an issue (somewhat recurring but not that hard to fix) since i’ve seen it commented somewhere around here before.
Thanks guys ! Had the same issue.
Got it resolved by selecting the correct auth profile.
thanks your reply helped me
Hello,
I am also getting same error as
Error writing to TransactionOk.value: Bad_AccessDenied("User does not have permission to perform the requested operation.")
I am getting error while writing back to OPC tag in transaction groups.
Can you help me with this.
You should probably start a new topic with additional details, like what OPC server you are even connected to.
Created new topic.
I am connecting to siemens sinumerik one S7-1500 OPC-UA server.
