You are using subscription-based license model. After the upgrade to the 4.x version you've got an error:
With the release of 4.0.0 version, we've introduced Connections. Every Relation is transformed into a separate Connection.
You have multiple connections with the same Destination instance. The subscription license you are using is based on the number of your subscription connections.
It is a known issue which has been fixed in 4.0.8 version. Please update the Exalate app to the latest version.
In case the error still remains, please do the following steps:
- Navigate to Connections
- Edit the Connection, which uses the same Destination Instance as another Connection
- Update Connection
The error should be fixed with the Connection update.
