I’m learning OPC UA using SIMATIC WinCC V8.1, but I’m facing an issue where the OPC UA Server service is not starting and shows “Paused” in Windows Services.

I checked the Wincc runtime is running and I have installed the licence for it and certificate for it.

Is there anything need to be checked. Thanks in advance.

I'm using an MTP1200 Unified Basic Panel with TIA Portal V21.

I created new users in Security Settings > Users, assigned roles and permissions, compiled the project without errors, and downloaded it to the panel.

​

However, after the download, I'm unable to log in with the newly created users. The panel either reports invalid credentials or does not recognize the users.
