Not able to send pushes since April 1st about pushok HOT 4 CLOSED

Seems something wrong with path name where certificate is located.
You should change /pathToCerts by real path from you environment:
$client = new Client($authProvider, $production = true, [CURLOPT_CAPATH => '/pathToCerts/']);

Hi, thanks for your quick reply. I used the real path name, just changed it to something shorter for this post. The certificates are located at the same location as my *.p8 file:
/var/www/virtual/myusername/AuthKey_xxxxxxx.p8
It's a shared hosting server. Do the files need special permissions?
The *.p8 file has 644, the certificates *.0 have 644

Hi, I got a little forward on that. Seems like the problem here is that curl was built with NSS and not openSSL.
If I build a new curl '--without-nss' (before I had to build nghttp2 also) and using this one I am able to connect to api.push.apple.com without any problems.
But PHP is using the default one with NSS and therefore it always fails.
I worked around by not using this library and call my custom built curl from php with exec() but that's far away from ideal.

Hi, just a quick update: The issue was related to curl 7.76.0 release which was done on 31st March (close to apples changes on 1st April). Thats why I thought this was because of Apple´s changes.
But the release of curl 7.76.0 broke http2 support for many ssl backends like NSS (not OpenSSL).
See this for details:

Now with a patch release curl 7.76.1 from yesterday everything is working.
