I am a comcast subscriber and ever since I upgraded my phone to a Galaxy S6 Edge I am getting the 43401 error. I have Verified my ID and password, and still I get the error. I can sign in the my account, connect and TV remote from the new phone, but not Home.

Yes, this is one cause of a 43401 error. Currently we only support log in with the primary username provisioned during account creation.
