Hi there, I am investigating to know why my server can no longer connect to Apple Push Notifications Services APNS (Failed to connect to APNS: 0) since about march 2017? It worked fine since 2014 till about march 2017? A test through www.pushtry.com is working properly! Did Apple make a change for side server, I didn't find anything about it ? Does anyone have an idea please? Thank you in advance.
