Proxy Authentication Required - AI Functions

Hi,

I am currently working remotely, and when I try to Refresh a report within Power BI Desktop I get the following error:

The report is using two of the Text Analytics functions; extract key phrases and sentiment score. When I was in the office refreshing worked perfectly fine, but now that I am working remotely I am seeing this error.

I can refresh any other reports within Power BI Desktop which do not use any AI Functions.

Can anyone assist?
