HTML5 Push notifications suddenly stopped working

Recently I configured HTML5 Push Notifications and it worked fine. Now the are working anymore. My configuration.yaml was not changed

In the logs I read: Missing ‘sub’ from claims. ‘sub’ is your admin email as a mailto: link.

Any suggestion?

I just noticed this myself. I realized it because I’ve got a HTML 5 Push Notification that I use to let me know when my phone has finished charging while I’m sitting at my desk so I can unplug it.

See also HTML5 notifications not working in 2021.4.0b5 · Issue #48766 · home-assistant/core · GitHub

I think it will be fixed soon.
