Error when saving report to Power BI Report Server

[Anonymous]

So I reviewed the documentation, identified the correct ports, etc. 

When I attempt to save a PBIX file from the Desktop for RS (launched either directly from my desktop or from the Power BI Server), I can see the subdirectories, on the server,  but when I attempt to save to those folders

I get an "An error occured while attempting to save the report to Power BI Report Server" 

When I attempt to upload a file from my desktop onto the Power BI server via Upload I get the following:

There was an error uploading your .pbix file. Verify that the file has not been corrupted and that the file extension matches the format of the file.

Can anyone help me figure out why I can't save to the server?
