Periodic 400 response

Newly jumping back into TVE after a very long absence. Using YTTV. Usually works. But For some channels, I will get a periodic 400 response, could not fetch the playlist. When viewing the request, I see the response returned is:

{"status":400,"message":"The job is not in running states. job id: "}.

I'll try again a few minutes later, and then it works fine. Curious if there is some issue on my end that is causing this?

On which channel

Sundance TV and FXM are two examples of channels I know it happened with.

I am getting 400 Bad Request Response with BBC America HD using Philo TVE.

No problems with those two channels this morning, but sigh, now getting a 404 for requests to dcs-live.mp.lura.live. Channel is News Nation.

I'd happily have this be user error, but not sure what I may have done wrong.

Oh, maybe that's covered by this: NewsNation unreachable - #7 by CraigG
