Is the support for Apple’s APNs (HTTP/2) enabled by default in aerogear-unifiedpush-server:2.1.0.Final?
Or is there any settings to apply to enable it?
Aerogear version: 2.1.0.Final
Errors are encountered when sending pushes to Apple using Apple certificates generated with the MacOS 11.1.
The error obtained is the following:
Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

With the old certificates we haven't anomalies, with the new ones we have the error above.
Any ideas?
It would be great to have support for web-push-notifications in a official closed version.
Is there an expected date for the release of the 3.0.0 version?
Windows is not used anymore, and this healthcheck:
Not enable the windows check
Describe the current/actual behaviour.
Describe all steps and pre-requirements which are required to be performed in order to reproduce this scenario. ( E.g 1. Action, 2. Action ... )
I'm getting the following error:

In 3 days, on a high demand server, this error happened 16029 times.
I think this error has been reported on 2016/Sep/08 in a Jira inside RedHat: https://issues.redhat.com/browse/AEROGEAR-5840
Checking the error stack the error appear at the addInstallation() method on the ClientInstallationServiceImpl class.
