Edge Sync broken - is https://edge.microsoft.com down

Edge sync when using a Microsoft Account is broken (including latest update 157.0.4341.46): when you close Edge and then go back in, the Profile Sync state gets stuck in "setting up sync" and never completes this stage and never sync's the data.

If you logoff from the account and then reconnect to the account, the sync gets setup correctly, but again fails the next time you close Edge.

This is an issue that has been happening across multiple machines running Windows 11 and multiple Microsoft accounts for probably around a month now. Not tested with Google or Apple accounts. Note that this issue is not occurring on Edge on Android (current version 157.0.4341.42).


I have done the following steps to try to address this issue (when correctly connected and sync'ing). Most of these I'd done previously, but following AI response, also checked a few other things:

  1. Re-sync data, did not help
  2. Reset sync data from Microsoft servers (have disconnected profile everywhere else), did not help
  3. Checked edge://sync-internals/ and sync is enabled, nothing obvious as error
  4. Checked edge://signin-internals/ and no apparent issues there either
  5. Checked edge://policy/ to confirm no policies stopping sync

Then checked the following endpoints, as suggested by the AI response:

  1. https://edge.microsoft.com which shows error
       <h2>Our services aren't available right now</h2><p>We're working to restore all services as soon as possible. Please check back soon.</p>0mC/0agAAAACaaBKpf8m9TLHwwMctrDZRTE9OMjgxMTgxNzA5MDYwAEVkZ2U=
    
  2. AI also suggested testing the endpoints for https://.cloudmessaging.edge.microsoft.com and wss://.cloudmessaging.edge.microsoft.com but could not work out what exactly to test for these.
