We have got a critical Quick OPC license issue on our quite normal working app today. We haven't done any changes on the server where the app is running, or on the application.

When we try to browse OPC server or read OPC items we get always following exception:

Failure Browse Servers: Not allowed to run by the license "Multipurpose". You might be running a trial license, and the version of the software you are using is obsolete. To resolve this problem, a) obtain a recent version, or b) ask for an evaluation license key, or c) install a license valid for the current version.
Product information follows. Component name: "QuickOPC", license IDs: "Multipurpose", version number: 571, release date: 6/9/2023, trial validity: 397 days, option expression: "EasyDAClient".
Context: 0 dropped license(s).

What could be the problem? Everything was running until now quite normal. (I mean we are using it for few years without problem).
Why is the license now recognized as atrial license? It is explained that it has a trial validity of 397 days an probably it has expired.

Could you support urgently? Our app cannot be used anymore.

Our app is built on VS 2022 .NET7 QuickOPC Version is 5.71.401. Also when I rightclick the dll's in my output directory I see the same version.

I have just checked with Lİcense manager whether everything is OK. But when I opened it I see there not my existing lcense. I can also not install it, as the insatll button remains inactive.
