Push notifications not working

まず Safari と Chrome での動作を再現し、service-worker の登録、Send Test Notification アクション、および /api/v3/plugins/web-push/test へのリクエストを確認します。ブラウザーのコンソールと、サーバーの無効な CSRF token に関するログを比較します。通知を有効にした状態が保持され、影響を受けるブラウザーでテスト通知とチャット通知が配信されれば完了です。

I can't get push notifications to work.

In Safari, nothing related to push notifications is working. If I toggle the "Enable push notifications on this device" switch, the "Currently notifying x device(s)" count doesn't increment, and when I refresh the page, the toggle is off again. If I click "Send Test Notification", regardless of whether "Enable push notifications on this device" is on or off, nothing happens (no "Cannot send test notification as push notifications are not enabled on this device" warning and no /api/v3/plugins/web-push/test request in the network tab of the dev tools). There's also no "ServiceWorker registration succeeded" message in the console, but there aren't any error messages either.

In Chrome, the service worker registers successfully, and I can enable push notifications, but I can't send/receive them. If I click on "Send Test Notification", I get an error message in the console: Failed to load resource: net::ERR_CONNECTION_CLOSED /api/v3/plugins/web-push/test:1. If I send myself a chat message from another account, I get an in-app notification, but no push notification and no error message.

I'm also seeing this error on the server:

2025-04-09T18:46:53.799Z [4567/124] - error: POST /api/v3/plugins/web-push/test
invalid csrf token

However, that error only appears once, and I've attempted to send several notifications, so I'm guessing it's not the root of the issue.
