Hi everyone, 
Im trying to load my data to power bi , i have around 10columns and almost 20k rows , its taking too much time and lead to connection timeout. Im using import mode as its the best way for me and the database is multidimensional. Any suggestions or advice ?

this is the error that i get 
DataSource.Error: AnalysisServices: The connection either timed out or was lost.

DataSourceKind=AnalysisServices
