Hi,

I have a scale-out architecture (front-end and back-end gateways) and a MSSQL database.

On the back-end gateway, I've setting up the tag provider and the historical provider. It works well.

On the front-end gateway, I have the read-only tag historian license. so I can retrieve historian data to show on trend on the clients. It works well too.

Each gateways are connected to the database.

But in the front-end gateway web page, in the section "Config \> Tags \> History" I have a "Demo expired" message on the provider create by the database connection.

And in the front-end gateway's log I have this error

Can I disable the tag history provider for the database connection ?

All licenses are correctly activated.
