I use Charles Proxy during development, and recently I've been seeing a lot of requests to init.sandbox.push.apple.com which results in HTTP 503. A quick ping says that this server does not exist.
When this occurs, I also noticed that push notification for my app that I'm working on fails.
The last time this occured, a quick update to a new iOS 13 version that was available at that time fixes it. However, this issue seems to be cropping up again with the latest iOS 13.3.
Anyone else facing this same issue?
As I am posting this message, I noticed another test device failing with HTTP 503 on health.apple.com aside to the above server.
Thanks
