Midnight interruption in Disney+

We watch movies on Disney+ late at night and every night I get a "no internet" message exactly at midnight. If I bail out of the app at 11:59, and wait a minute or two, I can get back in with no further interruption, but otherwise I often have to restart the cable box. Is this a known issue?  I did chat, and the agent said there was no way to fix it without talking to them when the problem was occurring ((i.e., midnight).  This doesn't seem like a problem that's just my cable box.
