I have a MySQL data source that works perfectly fine in Power BI desktop. When I uploaded to PowerBI.com, it tells me it can't refresh because I need to update the credentials. So I've gone to the data source settings and attempted to update the credentials. It's been pinwheeling on save for minutes... I have tried 3 different browsers to no avail. I have no idea if there's an issue where the connection is being blocked or if something else is wrong because it does not time out and give me an error. How can I fix this? Help!
