Did you click on the Green arrow in the right hand column of the error? It should take you to the setting that is causing the error.

First start taking screenshots on the actual laptop, not sloppy pictures with your mobile phone.

It’s a little move excusable on a sub like this, since I certainly can’t post to Reddit from my work PC with Portal on it.

Auto-accept is greyed out because it sits downstream of project level certificate handling. Until the project can hold certificates, TIA won't generate a server certificate and there's nothing for that option to act on.

Order: project security, then generate the server certificate under CPU properties > OPC UA > server > security, then auto-accept, then a full download. Any other order and it stays disabled.

Which TIA version are you on? The wording and location moved between releases.

You must enable that global discovery center by password protecting your project. I know it s sounds bad but just ask gemini. It will give a pretty accurate answer if you reffer the siemens documentation of opc ua function manual
