Open Cloud Messaging Service API suddenly not being received in-game despite returning status 200

[AdministratorGnar]

Reproduction Steps

Attempting to use the https://apis.roblox.com/messaging-service/v1/universes/ API returns a status 200 but does not actually send anything to the game servers

API has been working fine for last few weeks. My game suddenly broke this morning despite making no changes for the past 2 weeks.

I did a manual CURL request and whitelisted 0.0.0/0, Roblox returned 200 but, despite subscribing to the topic in-game, nothing came through.

Expected Behavior

The API request triggers subscribed events in-game.

Actual Behavior

Nothing goes through to the game servers.

Same issue. Tried a new API key, different game, and other platforms to handle the POST request but still no in-game results, despite the 200 status code.
