Re: Unable to Connect to import or direct query reports

 Check your cached data sources. Once in awhile it seems like these can go bad, or a change somewhere to password or configuration impacted them.

You can edit or remove your cached data sources by going to File - Options and Settings - Data Source Settings - click on "Global Permissions" highlight the data sources that are effected and either update them or delete them and reconnect. This should resolve any connection error as long as all the permissions are there.
