We are experiencing the same problem in our organization (only some pushes arrive).
Error when fails:
java.util.concurrent.ExecutionException: io.netty.channel.AbstractChannel$AnnotatedSocketException: Network is unreachable: api.push.apple.com/2620:149:208:306:0:0:0:b:443
io.netty.channel.AbstractChannel$AnnotatedSocketException: Network is unreachable: api.push.apple.com/2620:149:208:306:0:0:0:b:443
Is there a subscription where Apple reports these network changes?
