iOS APNS - Failed to connect to APNS: 0

[Jean-Michel Metzger]

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.

Did your cert expire?

The cert are renewed and ok. As I wrote, I tested them through www.pushtry.com successfully.
