TV show images missing - suspected Pi-Hole issue

What domain does Channels access to retrieve TV show images? I suspect my newly-installed Pi-Hole is blocking it, but can’t figure out which domain is being Pi-Holed erroneously. The TV guide loads show names fine, just the images that are broken.

I have lots of Pi-Holed requests in my logs to e.crashlytics.com, settings.crashlytics.com, metrics.icloud.com, and ichnaea.netflix.com… but I don’t see why any of those would cause problems with downloading images. Any ideas?

They are loaded from tmsimg.com
