A database defined on [[Invantive Cloud/Invantive Cloud|Invantive Cloud]] is not reachable through Invantive App Online until it is allowed to be. Until then a request ends with:
```
itgenboe679
The database on URL segment '…' does not allow use with Invantive App Online.
Please configure the database on Invantive Cloud.
```
The URL segment named in the message is the database the request addressed.
## Allowing
Grant the access on Invantive Cloud, not in the request:
- log on to Invantive Cloud;
- open the screen of the database concerned;
- tick "Allow Invantive App Online Use";
- choose "Save".
The permission is a property of the database, so it holds for every application module which uses that database, and it is granted once.
## Why It Is Off by Default
A database reachable through App Online can be addressed over HTTP by whoever holds the credentials, without the Invantive Cloud interface in between. Making that a deliberate choice per database keeps a database which was only ever meant for interactive use from being exposed by an application module written later.
