Playback is currently broken for a lot of people. Native Apple Music and music.apple.com still work. Cider does not.
What's going on
Google's Widevine update servers are handing out an older, broken CDM (4.10.3050.0). That version fails Apple's playback license check, so Cider shows License refused by the key server (-42585 / -1021) and skips tracks (or never starts them).
A fixed CDM already exists (4.10.3050.1 in WebView2, and newer Chrome can land 4.10.3112.0 after a manual update). The Chromium component updater is not serving that to Castlabs Electron clients, which is what Cider uses. So even a valid, already-signed Cider build gets the bad payload.
This is hitting macOS and Windows. Reinstalling, signing out, wiping app data, or resetting CdmStorage.db will not fix it. The updater is the problem, not your account.
What we're doing
We reached out to Castlabs here: castlabs/electron-releases#237
Waiting on a response. Once the updater starts serving a good CDM, clients should just start working again. We don't have a date yet.
If you're hitting this
Please don't file another issue. There isn't a local workaround we can ship until Google's updater is sorted. Sit tight, or keep using Apple Music / the web player in the meantime.

Not this: #1669 (older first-play license spam), #1878 and the Windows Machine Type Mismatch pile.
