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

Thanks for meeting us here in our community about the trouble with publishing with the Power BI Desktop while connected to our XB8, @th340385. I'm sure this can make it difficult to get your work done. We'll be happy to help. Can you tell me if Power BI Desktop has ever published while connected to the XB8 or is this a new issue? Is the XB8 new to your service or is the Power BI a recent addition?

Yes, I have published a ton of reports historically on the XB8, it is not new to my service.

@th340385 Okay, so it's a new issue. Have you rebooted your modem recently? This is just to ensure the XB8 has all the updates. If not, I recommend you do that first, and then retest. This will ensure the modem has all the updates.
