Unable to log in (US) since 2024-11-15

Something happened on Friday, Nov 15 that broke my ability to log in to the US servers.

When this URL is fetched:
https://clcloud.minimed.eu/connect/carepartner/v6/discover/android/3.1

The US region's SSOConfigureation URL (https://carelink.minimed.com/configs/v1/sso_cp_us_v6.json) returns a 404. The EU URL (https://carelink.minimed.eu/configs/v1/eu_sso_cp_eu_v6.json) still works:

"CP": [
  {
    "region": "US",
    "SSOConfiguration": "https://carelink.minimed.com/configs/v1/sso_cp_us_v6.json",
    "baseUrlCareLink": "https://carelink.minimed.com/api/carepartner/v2",
    "baseUrlCumulus": "https://clcloud.minimed.com/connect/carepartner/v6",
    "baseUrlPde": "https://clcloud.minimed.com/connect/pde/v2",
    "baseUrlAem": "https://www.medtronic.com/content/dam/emc"
  },
  {
    "region": "EU",
    "SSOConfiguration": "https://carelink.minimed.eu/configs/v1/eu_sso_cp_eu_v6.json",
    "baseUrlCareLink": "https://carelink.minimed.eu/api/carepartner/v2",
    "baseUrlCumulus": "https://clcloud.minimed.eu/connect/carepartner/v6",
    "baseUrlPde": "https://clcloud.minimed.eu/connect/pde/v2",
    "baseUrlAem": "https://www.medtronic.com/content/dam/emc"
  }
]

I'm not sure how to diagnose what is wrong. I can still log in fine via the Carelink iOS app, but I'm not able to proxy the traffic because of iOS SSL pinning so I can't see if the discovery URL has changed.

Any suggestions for things to try would be greatly appreciated!
