The subscription plan '***' of '****' does not allow access to Exact Online subscriptions of entrepreneurs such as '****'

I am having the below error while connecting to Exact Online after using the correct Invantive Bridge Online:

DataSource.Error: OData:
Request failed:
The remote server returned an error: (500) Internal Server Error.
Details:
DataSourceKind=OData

In the system report I have the below message:

The subscription plan '***' of '****' does not allow access to Exact Online subscriptions of entrepreneurs such as '****'. Please use another subscription plan or another contract than '*****'.

More information on this error can be found by following the hyperlinks in Bridge Online Monitoring below the error or directly:
