Hi All,
I am trying to understand an error in my Power BI Report server. From the RSPortal log, I see the following exception:-
2019-03-18 11:09:49.2806|ERROR|10|Servername\Username IP: GET /assets/js/app-94d0de55-a127-4102-9c10-c55fed72eceb.js - 0:00:00.1208755

Can someone please help me understand what is it related to? I have replaced the actual server name, user name and IP with placeholders above. (Servername\Username IP)
Thanks
Did you rename the virtual folders from the default? If so, this thread may help.
