Just updating in case anyone else stumbles upon this problem and figures out why it’s happening, or can provide Elan with new information.
Elan looked at the logs and has confirmed a 401 error.

This is the same problem described in a couple of other posts previously. Here and here, to give as few examples.
Unfortunately Elan hasn’t been able to figure out why it’s happening. There’s something going on with shared libraries, but it’s not happening to everyone. We also tried to eliminate PlexPass as the reason. It makes no difference whether it’s a PlexPass acount or not, when this error is happening. The error has been around a while, and there’s no obvious reason explaining why.
Hopefully someone else can help figure out what’s going on in the future. It’s annoying, but currently we’re stuck at a dead end.
