error log

Hi All,

I am trying to understand an error in my Power BI Report server. From the RSPortal log, I see the following exception:-

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
