Power BI & Xfinity XB8 Gateway

I have an (XB8) and am receiving an error within Power BI desktop when attempting to publish to any workspace on Power BI online. When connecting to a mobile hotspot or a non-Xfinity gateway (work wifi, other wifi, etc.), the error stops and I am able to successfully publish my workspace.  

The error reads two different ways:

'Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.'

'The underlying connection was closed: An unexpected error occurred on a receive'

It looks like this was an issue reported by another user. See link for reference to older post: ‎Power BI & Xfinity XB8 Gateway | Xfinity Community Forum
