publish/refresh issue

I am also having enterprise gateway/publishing/refresh issues starting today. The problems are all occurring on reports that have not changed and that have been working properly. First I was getting an error that the there was no Gateway installed (when there was). I reinstalled the Gateway to ensure I had the most recent version. I removed the reports from the web application and republished them as well and readded the data sources to the Enterprise Gateway. Now I am having two issues: 1. Datasets not updating and giving the message 'You can't schedule refresh for this dataset because one or more sources currently don't support refresh'. I have confirmed that all data sources are in the gateway - sources include excel files, CSV files and a SQL database connection which all updated with no issue in the past. The reports/data sources have not changed. 2. Cannot publish new reports from the desktop app to the web app. Tried creating a simple report with a single data source (CSV file) to test and when trying to publish, the below error occurs: Error Message (full message is too long so could not insert in this comment box, so this is the first part of it): Publishing failed for an unknown reason. Stack Trace: Microsoft.PowerBI.Client.Windows.PowerBIService.PowerBIServiceException: Publishing failed for an unknown reason. ---> System.InvalidOperationException: Publishing failed for an unknown reason. ---> System.Web.HttpUnhandledException: Response Body: {"id":"07385791-a592-4f27-89ee-c6f5dcc1e905","importState":"Failed","createdDateTime":"2016-06-0
