Hi, I have configured the OPC UA Server Setting in the Ignition, but when I try to connect with the server from the Prosys UA Client, it doesn't connect. ![Screenshot_12](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/e/1e66dca5f29794835229a5e8908781fed3a2f12c.png) When I press the **select** , it returns to the same window. I am not sure how to debug what is wrong... ---

what's the error message in Prosys? try ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/2/121eaa5564d6e99a1ab5e82f3a151dd5cbd4cac2.png) ---

That URI looks suspicious--that is, that doesn't look like the URI for an Ignition server that is configured to listen to connections from the outside world. Look here: [https://docs.inductiveautomation.com/display/DOC81/Ignition's+OPC+UA+Server#Ignition'sOPCUAServer-OPCUAServerSettings](https://docs.inductiveautomation.com/display/DOC81/Ignition%27s+OPC+UA+Server#Ignition'sOPCUAServer-OPCUAServerSettings) ---

Hi All, Thanks for the response. I don't see any error in the logs of Prosys. I have also Unchecked the Anonymous Access Allowed. Below are the configurations from Prosys ![Screenshot_12](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/e/1e66dca5f29794835229a5e8908781fed3a2f12c.png) ![Screenshot_13](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/2/a2a23e8bd9867ebe5f4fa4efdc445380d1e8f9bb.png) ![Screenshot_14](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/7/f7060b2fa21929c58194582c0f24e93b2c730671.png) Prosys and Ignition are on the same PC ---

Did you add the user 'prosysuser' in the opcua-module user source? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/c/4ccd863c268f84dd380898ea7af4fcd75be3dbba.png) ---

It looks like you made a new user souce, not add the user to the user source I referenced. ---

Yes, It was not working for some reason, so I created a new one, does this change anything ? ---

The default user source for the OPC-UA module is 'opcua-module' (as seen in @Yousef_Ali's post). ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/7/37589642db8b9f5ad9973574893ff76a1e6336d5.png) Any users should be added to that user source. Also, restating @pturmel's post: > [@pturmel](#): > > that is, that doesn't look like the URI for an Ignition server that is configured to listen to connections from the outside world. Did you enter that URI, or did Prosys fill that in for you? ---

Kind of a little confused. Do we need to install an OPC UA Module Driver to appear URI? as of now I don't see ant option of URI ---

Might be easier if you screenshot your OPC server settings inside Ignition including the users in the user source you're using. That way we can see what you're seeing. It may just be a simple configuration change, but if we can verify that the server settings are OK, it helps everyone narrow down the issue. ---

bumping an old thread... the URI is auto-populated by Prosys when detecting a server
