Legacy FCM doesn’t work anymore since the weekend.
My devices send push notifications via Legacy FCM via fcm.googleapis.com/fcm/send. I didn’t change anything, but since the weekend I get the error code “HTTP/1.1 403 Forbidden”. Does anybody else have this problem since a few days?
Changed google something?
I tried my keys with https://www.apnstester.com/fcm/ It still works. So I think google changed something in the firebase console.
Is it possible that there is a secured access needed (https) and http is not supported anymore.
