Roku with Xfinity Stream not working from second hone

I have two homes. Both with Xfinity service. Both accounts are linked to my user id.

I want to watch recordings from home 1 at home 2 with the Stream app on my Roku. It doesn’t work. I get an error message. If I set default as home 2 it also doesn’t work.

Amazon Fire tv works fine. I see all home 1 recordings and channels at home 2. Roku doesn’t work.
