Facing problem with APNS push services at client end. Server side is ok and it sends push to APNS properly as particular devices get stuck at some moment. Here are the server logs.
VOIP Push: Push notification waiting by APNs gateway.
VOIP Push: Push notification accepted by APNs gateway.
Here are the console logs of effected device

回答1:
Encountered a similar situation where no push was arriving, and dns errors were logged when querying sandox.push.apple.com
A fix was to change the phones to use an alternative DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1) in the wifi settings.
